Overview
The new switching family, called SWITI, provides a complete and cost-effective solution for all switching systems. The family is divided in two sub-families, the MTSI family and the HTSI family. The Preliminary Data Sheet describes the functionality and characteristic of the HTSI devices. The devices can be used in today's switching applications, e.g. conventional PBXs and central offices (CO's), as well as in H.100/H.110 applications (only the HTSI family), which are the key to high performing CTI- and Voice-over-IP-applications, one of the most important future technologies in telecommunications. The main requirements of today's switching applications are met by the following features: * Constant delay e.g. to support wide band data switching, or channel bundling * Bit switching/subchannel switching to support applications such as mobile base stations, DECT, computer telephony In addition, the SWITI family provides new features to ensure a broad range of configurations to make it possible to adapt the device to all switching applications: * * * * A compliant H.100/H.110 interface (HTSI) 8-channel stream-to-stream switching capability (HTSI) Message mode, which allows to assign a preset value to any output time-slot GPIO (General Purpose I/O) port, which is controlled from the external P
SWITI family. The SWITI family consists of 6 ICs with different switching capacities. The possible configurations are shown in Table 2. The HTSI versions provide an additional H.100 / H.110 interface, while the MTSIs are standard switching devices. All devices can be programmed easily, thus helping the designer/programmer to integrate the device into his application comfortably.

Overview
H-Bus I/O 32 -
HTSI devices. The HTSI devices can be operated in two different modes, H-Mode and M-Mode. In H-Mode the device offers 16 local I/Os and additionally a compliant H.100/H.110 interface (32 bidirectional I/Os). The complete number of available connections can be assigned as H-bus to H-bus, local bus to local bus connection, or mixed. In M-Mode all lines are configured as local I/Os, so that in total 32 local I/Os are provided. Thus e.g. the HTSI-XL device can be used as 2K non-blocking switch operating with all 32 I/Os at 4.096 Mbit/s.

Features in Detail
Flexible Data Rates Each input and each output line of the local bus is programmable to operate at different data rates. The possible data rates are 2.048 Mbit/s, 4.096 Mbit/s, 8.192 Mbit/s, and 16.384 Mbit/s. Even for the HTSI in M-Mode all of the 32 input lines and 32 output lines are configureable, except for the bit rate of 16.384 Mbit/s. In case of 16.384 Mbit/s only 24 lines can be used. The possible data rate for the data lines of the H-Bus are 2.048 Mbit/s, 4.096 Mbit/s and 8.192 Mbit/s. Constant and Minimum Delay Each connection independent of the addressed buses can be determined to be a constant delay or minimum delay connection. Constant delay means that any input timeslot or subchannel is available on the programmed output after 2 frames. Minimum delay means that the time-slot or subchannel appears at the output as soon as possible. The minimum delay depends on the chosen connections and the possible range is between 0 and 2 frames. Subchannel Switching Each connection can be a 1-bit, 2-bit, 4-bit, or 8-bit connection. Subchannel switching is applicable to both the local bus and the H-Bus and has a constant delay of 2 frames. Sub-Channel switching is supported only for data rate of 2.048 Mbit/s, 4.096 Mbit/s and 8.192 Mbit/s. Programmable Clock Shift The position of time-slot 0 of each local bus input line can be programmed within the time-slot before and after the PFS rising edge in half clock steps. Also the position of time-slot 0 of all local bus output lines can be programmed within the first time-slot after the PFS rising edge.

PRELIMINARY 8-Channel Stream-to-Stream Switching
Overview
This feature offers the possibility to efficiently switch one data stream to another at the same or different data rates without occupying switching memory capacity. It mainly supports interoperability between CT-bus (Computer Telephony) devices such as SCbus and MVIP-90 running at different data rates. It is possible to use up to 8 lines from the H.1x0 data lines to establish the connections. Input and output frequency can be configured differently. Automatic Data Rate Adaption Connections are also possible between lines operating at different data rates. The programmer just specifies input and output line, time-slot, and if necessary, the subchannel. Parallel Mode The first 8 local bus input and output lines can be configured to one parallel input or output port respectively. In serial mode a time-slot is determined by 8 consecutive data clock cycles according to each line. In parallel mode a time-slot is determined by 1 data clock cycle according to the first 8 lines. Broadcast With this feature it is possible to distribute one incoming time-slot to different output timeslots. Multipoint Multipoint connections can be seen as the opposite of broadcast connections. Here it is possible to generate one output time-slot consisting of several input time-slots. The specified input time-slots are logically AND or OR connected (selectable) and have a constant delay of 2 frames. Read Access The programmer has access to any input time-slot. After issuing an appropriate command the arrival of the time-slot will be reported by interrupt. The value can be read from a dedicated register. For every read request the command has to be issued again. Message Mode (Write Access) This feature allows a constant value to be sent to any given output time-slot.

PRELIMINARY Framing Group
Overview
It is possible to specify up to 8 different framing signals of 8 kHz. The position of the rising edge and the pulse width can be programmed for each signal. The reference frame is determined by the PFS signal. The pulse parameters are programmed in half step resolution according to a 16.384 MHz clock. General Purpose Clocks All 8 GPCLK lines can be configured as individual clock outputs with 8 kHz, 2.048 MHz, 4.096 MHz, 8.192 MHz, 16.384 MHz and for test purposes with the internal frequency or the input frequency of the analog PLL (APLL). GPIO Port Each line of the general purpose input/output port can be configured to be either input or output. According to an input an edge causes an interrupt. The outputs can be influenced by write access via the microprocessor interface. Thus the user has the possibility to observe and influence additional signals for his application. Microprocessor Interface All devices provide a standard 8-bit microprocessor interface operating in either Intel or Motorola mode. Optionally it is possible to configure the GPIO port as additional data lines to provide a 16-bit microprocessor interface. The use of the 16-bit P interface reduces the number of write cycles required to configure a connection from 7 (in case of 8-bit P interface) to 3 write cycles. Input/Output Tolerance The HTSI can be used in a 5 V environment with two additional 5 V (VDD) power supply pins. Local input and outputs are 3.3 V and 5 V tolerant. The outputs have TTL level driving capability. The H-Bus lines of the HTSI can be used in a 3.3 V signaling PCI environment.

The HTSI is dedicated to perform time-slot switching between the local bus and the HBus or to offer a solution for applications with a high number of local I/Os. The HTSI operates in two modes. In H-Mode (Figure 1) it works with the H-Bus and in M-Mode (Figure 2) it operates without the H-Bus. The HTSI in H-Mode provides 16 PCM input lines and 16 PCM output lines and the complete H-Bus with 32 bidirectional H.100/H.110 data lines.

Typical Applications
Typical applications of the SWITI family are: * PCM switch, concentrator or multiplexer in PBXs, COs or mobile base stations * H.100/H.110 interface in - Computer telephony systems - Internet telephony systems - LAN/WAN access devices - Enhanced service platforms The following sections give a general overview of the system integration of the SWITI family.
1.4.1
Standard PBX or CO Application
The MTSI or the HTSI in M-Mode can be used, just as the MTSC or MTSL, in standard private branch exchange or central office applications (Figure 3), e.g. in the switching network.

Computer Telephony Application
In Computer Telephony Integration (CTI) applications, resources such as the analog telephone line cards, ISDN ports, switching controllers, FAX firmware, or voice processing modules are in the form of plug-in cards that sit on the ISA or PCI slots of a PC. Resource sharing is established by connecting the top of the plug-in cards with cables. This Time Division Multiplex (TDM) bus has evolved from the original H-MVIP, MVIP-90, Dialogic's SC-Bus, into the latest H.100/H.110 bus or H-Bus developed by the Enterprise Computer Telephony Forum (ECTF). By connecting to the H.100/H.110 interface devices, system modules may send and receive data to and from any one of the 4096 TDM time-slots of the H-Bus. The H-Bus also offers the ideal solution for routers to provide a bridge between the data communication and telecommunication system modules. In Computer Telephony (CT) environment, resource sharing is accomplished by passing data back and forth through the H.100/H.110 bus. Figure 4 shows the example.

Overview of Functional Blocks
Switching Factory The switching factory is responsible for transferring and handling the incoming data streams to the assigned output channels and time-slots. The block includes a 512, 1024, or 2048 byte input and output data memory as far as an input and output connection memory. Local bus and H-Bus I/O Block The block is designed to handle the conversion of the data provided via the switching block and the external PCM and H.1x0 interface. It performs the PCM and H.1x0 timing, the data rate selection and the tristate control. Microprocessor Interface Block A standard 8-bit multiplexed or de-multiplexed P interface is provided, compatible to Intel/Infineon Tech. (e.g. 80386EX, C166) and Motorola (e.g. 68040, 68340, 68360, 801) bus systems. If the GPIO port is not needed it can be used to provide a 16-bit P interface. GPIO Block This block supports up to 8 external port lines each one configurable as input or output. A change on an input line may cause an interrupt (if not masked). The user has access to the port configuration and information via the appropriate registers of the P interface. PLL and Clock Block The PLL generates all frequencies supporting the H.1x0, SCbus, MVIP, H-MVIP busses. The internal phase-locked loop (PLL) generates all bus frequencies synchronized to a selected reference signal. The output frequency tolerance is equal to the input frequency tolerance. The PLL operates from a 16.384 MHz, or 32.768 MHz external crystal, oscillator. According to the H.1x0 specification the input frequency tolerance must be 32 ppm or less.

Switching Factory
As shown in Figure 8 the switching factory comprises the input/output data memory and the input/output data handler with the programmed connections. The I/O controller handles all lines operating at the same or different data rate. To establish a connection the user must only program the source line with time-slot and the destination line with the time-slot. The internal controller (data handler) writes the connection in a connection descriptor list and stores this list in the connection data handler. The programming procedure is described in Chapter 6. The incoming time-slot will be stored in the input data memory controlled by the input handler. The output handler controls the constant, minimum delay and subchannel switching.
3.3.1
Switching Modes
The SWITI family supports a various number of switching modes. All modes are described in the following chapters.
3.3.1.1
Minimum and Constant Delay
Each connection independent of the addressed buses can be determined to be a constant delay or minimum delay connection. Constant delay means that any input timeslot or subchannel is available on the programmed output after 2 frames. Minimum delay means that the time-slot or subchannel appears at the output as soon as possible. The minimum delay depends on the chosen connections and the possible range is between 0 and 2 frames, up to 3 frames in rare cases. An application note which describes the possible connection and minimum delays is available.
3.3.1.2
Subchannel Switching
Subchannel switching is applicable to both the local bus and the H-Bus and has a constant delay of 2 frames. Every connection can be 1-bit, 2-bit, 4-bit, or normal 8-bit connection. It is possible to combine every kind of subchannel connection, e.g. two 1-bit time-slots with one 4-bit time-slot to one output time-slot. Please refer to Chapter 6.11.2 for a detailed description about the programming.
3.3.1.3
Multipoint Switching
As described in the overview the multipoint-switching allows to switch several input timeslots to one output time-slot. All input data are logical AND or OR connected. This mode is selectable with the multipoint connection command. The setup (logical AND or OR) for the last connection determines all other previous programmed multipoint connections. Multipoint switching has always a constant delay. Subchannel switching is not supported.

3.3.1.4
Broadcast Switching
Broadcast switching allows to distribute one incoming time-slot to different output timeslots. The input and output mechanism is the same as the normal constant delay connection mode with subchannel switching. Minimum delay is also supported without subchannel switching. A table with the possible connections and minimum delays will be provided. The broadcast connection is programmed in the same way as a normal connection. The output time-slots can be released with the disconnect part of broadcast command. The last connection must be released with the normal disconnect command. Subchannel Broadcast It is possible to program one input time-slot as broadcast subchannel connections. That means the bits from the input time-slot are used in several broadcast connections related to one ore more output time-slots. The output time-slots must be released with the disconnect part of broadcast command. The last subchannel connection must be released with the normal disconnect command. (Please refer to Chapter 6.11.4 for an example)
3.3.1.5
Bidirectional Switching
The input and output mechanism is the same as the normal constant delay or minimum delay connection. The exception for the internal data handling is explained in the following figure. Since the internal state machine has to calculate the belonging connection the time to program a bidirectional connection is twice as the time to program a normal connection. There is a special command to program a bidirectional connection. A bidirectional connection can only be programmed on a available time-slot and input/ output line.

Stream-to-Stream Switching
The stream-to-stream switching connection supports the interoperability for the H.1x0 bus with the MVIP and SCbus, it doesn't support the local bus lines. Every dataline can be selected for the operation. The maximum number of switching channels is eight. The following example on page 29 is using two switching channels. The stream-to-stream connection can not be established parallel to the normal connections. The output of the stream-to-stream switch is multiplexed with the output of the switching factory, with the stream-to-stream having priority. Every stream-to-stream connection must be programmed with the special command in the CMD1 register. To establish the connection the bit I2 must be set to 1 and to release the connection the bit I2 must be set to 0. If the bit I3 is set to 1 all stream-to-stream connections will be released. The STR bit in the ISTA1 register indicates that one or more stream-to-stream connections are set (see also Chapter 6.2). A internal control

Architectural Description
logic avoids a wrong selection of the possible stream-to-stream connections and thus prevents bus collisions. The main application of the stream switch is to provide an inter-rate exchange highway allowing legacy bus devices to exchange data even though they operate at different rates with a minimum delay of zero frames. The stream-to-stream connections starts with the first frame and the switching possibilities are determined by the highest bit rate and can be seen as a repetition of same time-slot (TS) connections from one data line to another data line. If the first TS switching sequence is finished it starts with the same sequence from the next available time-slots. Table 10 shows the possible time-slot connections.

Message Mode
The message mode allows to send a predefined 8-bit data value in a defined time-slot on a dedicated destination port. Message mode is started or stopped via register CCMD. The data value to be send is predefined in register MV. The time-slot and the destination port is is defined in register OTSA and register DPA.
3.3.2
Parallel Mode for Local Bus
The parallel mode can be set with the 'set parallel mode' command in the configuration command register. This command set the first 8 input lines and the first 8 output lines of the local bus as parallel bus. The data rate for all lines must be 2.048 Mbit/s. If the parallel mode is enabled all included lines will be set to 2.048 Mbit/s automatically. If the parallel mode is disabled all lines will keep the data rate of 2.048 Mbit/s until a new data rate will be programmed for the selected line. The internal S/P-converter is bypassed. The 8 bit data stream per time-slot is distributed on 8 data lines, one bit for every line. The least significant bit is assigned to line 0 and the most significant bit is assigned to line 7. To program a connection line 0 must be used for this special parallel data port. The bit shift value must only be programmed for port 0 and this value will be assigned to the other 7 ports automatically. The initialize sequence is described in Chapter 6. The switching data handling is the same as the data handling for constant delay or minimum delay mode. A timing diagram is provided in the timing diagram chapter (see "PCM Parallel Mode Timing" on page 131).

3.3.3
Switching Block Error Handling
The normal procedure to establish a connection is explained in Chapter 6. The way to program a new connection for a specific time-slot and data line is to release the connection and to program the new connection. The SWITI switching concept provides an internal error handling to detect errors in the switching chain caused by a programming error. A programming error can occur because of noises on the data lines, software errors, etc. A programming error is defined as follows: - if a non existing connection (minimum, constant delay, or message) will be released. - or if a existing minimum delay connection will be established. If a programming error or a connection memory overflow is detected the interrupt bit CON in the IESTA2 register will be set. In this case the last connection which was tried to establish or to release is not valid. The switching mechanism is not affected and will continue with the switching process. For debug purposes the SWITI has the capability to write out the content of the complete connection memory and data memory via the microprocessor interface. This procedure is described in Chapter 3.3.4. It is recommended to track all established and connections with the specific customer application software. For debug purpose it is useful to compare the contents of the switching memory with the virtual connections in the application software.
3.3.4
Analyze Connection and Data Memory
With the special command "memory dump enable" in the connection command register (CCMD) it is possible to read the complete memory in a defined sequence from the CON register with a 8-bit P access. This feature can be used only for analyze purposes. The command disables the complete switching function as far as all data lines (PCM/ H.1x0) are set to high impedance. If the command is set and after the specific recovery time (200 ns) the connection chain and data memory can be read sequentially by a P access to the CON register. The internal controller writes the next 8-bit memory data in the CON register if the P read access is finished. That means there is a specific recovery time for the P to the next CON read access. The internal memory dump controller reads the present memory contents of the input chain memory, data memory and output chain memory. During the memory dump the internal state machine will loose the synchronization with the external frame structure. Therefore a software reset must be issued and the device must be programmed again, except the clock configuration.

Architectural Description
The SWITI clock generator provides all necessary clock signals for the SWITI PCM (local bus) and H.1x0 interfaces. Since the device is a H.1x0 master capable device there are two digital PLLs which can be locked to different network reference signals. The digital PLL synchronizes the external crystal or oscillator to the selected reference clock. The digital PLL (DPLL) will be bypassed if the selected reference signal is >= 2.048 MHz. The input signal for the analog PLL (APLL) is 2.048 MHz in normal operation mode. The APLL is used for multiplying the 2.048 MHz clock into a 49.152 MHz clock and to generate all clock signals for the PCM and H.1x0, and general purpose clock signals. The SWITI has an on-chip oscillator which allows the user to connect an external 16.384 MHz or 32.768 MHz crystal. Instead of using the crystal it is possible to assign a 16.384 MHz, or 32.768 MHz oscillator to the ECLKI pin. After the power-on or hardware reset the APLL is bypassed. The APLL will be synchronized (after approximately 750 s) to the external crystal or external oscillator if the command 'set external frequency' is set. This command must be used otherwise the internal working frequency is equal to the external input frequency and the SWITI will not work properly. If the APLL is locked the status bit 'APLL' in the ISTA1 register will be set. Note: After the reset it is necessary to program the correct crystal or oscillator value as first programming step. Otherwise the operation frequency for the SWITI is not correct.

These pins must be decoupled from the digital power (VDD/VSS), see also the available Application Note "Layout Notes".

The value of the output frequency depends of the programming of the n-divider. The chosen output frequency for the SWITI is 49.152 MHz and the input frequency is 2.048 MHz. The macro consists of a digital and an analog PLL which are working together. During start-up only the digital one is enabled and makes a coarse adjustment, so that the technology dependency of the circuit is compensated. Afterwards the digital PLL is disabled again and the analog one is switched on for normal operation. The digital PLL is of first order and consists of a frequency detector (FD), an up/down counter, a digital-to-analog converter (DAC) and a current controlled oscillator (CCO). The FD detects any frequency difference between the reference clock (fref: input clock fin = 2.048 MHz) and the divided oscillator clock. The output signal controls the counter. If the reference frequency is higher than the divided oscillator frequency the counter is increased. The counter output drives a current steering DAC which controls the input current of the internal oscillator. Its current rises and the output frequency increases until both frequencies are equal. The digital PLL is enabled after reset or power up and is disabled after 750 s (lock time of PLL). The counter keeps its value and the DAC output current irough is constant until the digital PLL is reseted.

Architectural Description
The second order analog PLL consists of a phase/frequency detector (PFD), a charge pump (CP), a loop filter and the CCO. The PFD which is sensitive to the rising edge detects any phase or frequency difference between the input clock (fref) and the divided output clock (feedback) and generates a control signal proportional to the phase difference. The output signals up and down cause the charge pump to modulate the amount of charge in the low pass filter (VTOI) for the integral part (iint) and to feed current into the CCO for the proportional part (iprop). With these two currents and the DAC output irough the CCO is controlled. If feedback is leading fref, the oscillator is too fast. The down signal is activated and the CP subtracts some current iprop. When fref is in phase with the feedback the PLL will hold the control current at that level and phase lock will be achieved. Thus through this negative feedback arrangement, the PLL causes the feedback and fref signals to be equal with minimum phase offset. If the analog PLL becomes unstable, a signal pllko is generated which resets the digital PLL.

3.4.3
Master-Slave Selection
For a proper working PLL and clock fallback mechanism it is necessary to select the part as master or slave with the "select master/slave" command in the CMD1 register. If the M-Mode is used it is not allowed ot use the special master command. As described in Chapter 3.4.6 this command must be used to finish the clock generator configuration and/or to finish the H.1x0 fallback configuration. The PLL reference source can be selected with the "PLL Primary Reference for Master Selection" command, or with the "PLL Source Selection" command.
3.4.4
Phase Alignment
If the phase alignment function is enabled all PLL output signals and the main divider are edge synchronized with the PLL clock input. If the selected reference signal is less than 2.048 MHz the edge synchronization resolution depends on the selected external crystal/oscillator frequency. If the phase alignment function is disabled the PLL output frequency (49.152 MHz) is edge synchronized with the PLL input frequency and the main divider output frequencies are edge synchronized with PLL output frequency. An example of phase alignment functionality is shown in Figure 14. Phase alignment is required to keep the output signals in phase relative to the input signals (e.g. C8A relative to C8B). After reset phase alignment is automatically activated in secondary master and slave mode and turned off in master mode. Note: The phase alignment should be disabled for all reference frequencies < 2.048 MHz.

PLL Synchronization
As shown in Figure 11 there are several possibilities to synchronize the PLLs. For the synchronization it is necessary to distinguish between the different operational modes (H.1x0 with PCM, only PCM). The PLL needs approximately 750 s to lock to the selected reference frequency. For the frame synchronization the clocking unit needs additionally two frames to synchronize the incoming frame with the generated frame. This frame synchronization will be enabled if the device is configured as H.1x0 slave, H.1x0 secondary master, and compatibility bus slave.
3.4.5.1
PLL Synchronization H-Mode
The following operational modes apply to the HTSI H-Mode. - H.1x0 Master and PCM Master In this mode the reference frequency must be selected by software according the H.1x0 specification. The H.1x0 and PCM clock synchronization is guaranteed by the fact, that the synchronized 2.048 MHz clock, generated from one of the digital PLLs, is used as input clock for the analog PLL, used for the generation of all necessary clocks. If the reference frequency is equal or higher than 2.048 MHz the digital PLL is bypassed and the reference signal is connected with analog PLL. The beginning of the PCM frame is equal with the beginning of the H.1x0 frame. - H.1x0 Slave and PCM Master For the H.1x0 Slave mode both digital PLLs are bypassed and the input signal for the analog PLL comes from one of the selected slave path clock sources. The PCM clock signals are synchronized to the H.1x0 selected input reference clock signal and there isn't a phase difference between the signals. The beginning of the PCM frame is equal with the beginning of the H.1x0 frame. This is guaranteed by the fact, that the related frame signal to the selected clock signal is used for the frame synchronization. - H.1x0 Master and PCM Slave This mode is not allowed, since the PCM frame start is not synchronized with the H.1x0 frame start. - H.1x0 Slave and PCM Slave The PDC and PFS signals must be equal to the highest selected PCM datarate and must be sourced. The incoming PCM clock/frame signals must be derived from the same clocking source as the H.1x0 clocks or from a master with the same reference clock as the H.1x0 master. Since there isn't a elasticity switching buffer in the SWITI the incoming clock must be synchronized, must have the same phase and the H.1x0 frame start must be equal to the PCM frame start.

3.4.5.2
PLL Synchronization M-Mode
The PLL reference source can be selected from the primary reference master source (PFS, PDC, NTWK_1/_2). If the selected reference signal is less than 2.048 MHz the main digital PLL is used to synchronize the analog PLL. The digital PLL is sourced from the external oscillator, or crystal. In this case the analog PLL output frequency tolerance is equal to the external oscillator/crystal frequency tolerance. Furthermore the analog PLL can be sourced directly from the external oscillator, or crystal, or from the PDC input. All generated output frequencies will have the same tolerance as the selected input frequency.
3.4.6
PLL Error Handling
The SWITI in H-mode has an integrated control logic to detect possible PLL configuration errors. If one of the errors (see below) occurred the clock fallback mechanism and the PLL functionality is not guaranteed. The control mechanism starts with the command 'Set as H.1x0 Master/Slave (HTSI H-Mode)' in the CMD1 register. That means that the mentioned command finished the clock generator configuration. As shown in Figure 11 there is a cntr. logic for the two APLL multiplexer implemented. The first multiplexer is used to select one reference source for the master mode and the second multiplexer is used to decide between the slave or master path. The main task for this control logic is to make sure that the input signal for the APLL derives from the internal oscillator (external oscillator) after the reset. The second task is to control the input signal for the APLL during the normal operation and to decide whether the programmed combination is correct. If one of the following combinations occur, the control logic selects the internal oscillator, resets the complete clock generator configuration and an interrupt will be generated (-> wrong PLL source programming). Configuration errors which will be detected: HTSI H-Mode Master configuration - PLL2 source was selected (slave path) HTSI H-Mode Slave configuration - PLL main or secondary master reference was selected Furthermore the fallback state machine controls the logic to multiplex the necessary signal for the fallback mechanism. Since there are redundant paths for the reference clock and also for the slave clocks the clock fallback time depends only on the multiplexer delay time.

Clock Signal Monitoring
To support the clock fallback mechanism the SWITI has the capability to monitor the CT_CA (CT_C8_A, CT_FRAME_A), CT_CB (CT_C8_B, CT_FRAME_B) clocks additional with the selected primary PLL reference, and to monitor the interoperability clock signals. The SWITI reports every clock failure to the host with a interrupt if it is not masked. If the interrupt is masked the status of the clock errors can be read from the IESTA1 and IESTA2 registers (polling). The H.1x0 clock signal monitoring will start immediately after programming a new reference clock. The process is finished with the command 'master slave' from the CMD1 register. The following monitoring requirements for H.1x0 must be meet: - A received rising edge of CT_C8_A/B (both signals must controlled independently) doesn't arrive within 35ns of the expected edge. or - There are not exactly 1024 clock periods per frame. If one of these requirements are not meet an interrupt will be generated (if not masked) to inform the system software that one of the clock circuits (A or B) is failed. The following monitoring requirements for the interoperability clock signals must be meet. The FR_COMP is monitored in conjunction with the selected primary PLL reference (master) signal or with the selected PLL source (slave). MVIP - A received rising edge of C2, C4, or C8, or C16 doesn't arrive within 40 ns of the expected edge. or - There are not exactly 256, or 512, or 1024, or 2048 clock periods per frame SCbus - A received rising edge of SCLK doesn't arrive within 40 ns of the expected edge. or - There are not exactly 256 (SCLK=2.048 MHz), 512, or 1024 clock periods per frame. NTWK Signals A received rising edge of the NTWK signal doesn't arrive within 80 ns of the expected edge.

Clock Fallback Mechanism
The clock fallback mechanism can be switched on with the special command "H.1x0 Fallback Mechanism and Clock Monitoring" and the related instruction bits. As described in the H.1x0 specification there are two different fallback path's in the fallback state machine. The instruction "fallback from main to secondary reference (primary master)" in conjunction with the command "automatic switch back to main ref." covers the "primary NTWK link fails" path. The correct reference (main and secondary) as described in the H.1x0 specification must be programmed, e.g. NTWK or CT_NETREF. The instruction "fallback from main to secondary reference (secondary master)" and "from A clock to B clock (Slave)" covers the "primary master clock circuit fails" path in the fallback state machine.

Clock Fallback of Primary Master
The primary master is synchronized to a reference clock (NTWK or CT_NETREF) and drives the CT_C8_A and CT_FRAME_A clocks. Figure 15 shows a configuration example. If the primary network reference clock (NTWK_1) fails the device automatically synchronizes to the secondary network reference clock (NTWK_2). If the primary reference clock returns the device may synchronize to it again automatically or by software command (depends on configuration). If not masked the failure is reported by an interrupt.

The loop command in the configuration command register CMD2 provides support for automatic PCM-PCM and H.1x0-H.1x0 loops. - PCM-PCM loop All input lines are pad connected with the corresponding output line. H.1x0-H.1x0 loop The first 16 H-bus lines are pad connected with the corresponding upper 16 H-bus lines. e.g. H0 -> H16; H1 -> H17; ....... After the loop disable command was set the lines will be set in high-impedance after approximately two frames.
3.6
Read SWITI Configuration with Indirect Register Addressing
Since the SWITI configuration can be programmed with defined instructions in the CMD1 and CMD2 registers it is possible to read the current configuration through the indirect access registers. The indirect addressing is started by writing one of the five read configuration commands in the CMD2 register. The five commands can be separated in two groups, internal configuration and external line configuration. The internal configuration, e.g. clock generator, IREQ pin can be read with command "Read Configuration". The internal settings are decoded with the instruction bits I3..0. The data rate for the PCM and H.1x0 interface can be read with the "Read PCM / H.1x0 Line Configuration" commands and to get the GPCLK line configuration and the bit shift value the "Read GPCLK Configuration" and "Read Bit/Clock Shift Configuration" must be issued. The TSV and CON registers contain the required information after the internal read process is complete. The recovery time is 240 ns. To read the correct configuration data from the TSV register it is not allowed to use the command "Read Time-Slot Value" before the TSV register has been read.

Power-On and Reset Behavior Hardware Reset
There are three independent low active reset pins: RESET, CT_RESET and TRST. If the RESET or CT_RESET (in conjunction with the mode pins M-Mode and H.110 Mode) pin is activated, it immediately places all outputs and I/O ports into tri-state, except the ECLKO pin. After the reset process the correct external frequency must be set with the command 'Set external frequency' accordingly. This command starts the configuration process for the APLL. The APLL is locked after 750 s. During this period the APLL is bypassed and the internal frequency is 2.048 MHz. If the APLL is locked the internal frequency will be 49.152 MHz. Individual output sections must be enabled by setting the command in the configuration command register CMD1, or CMD2. Internally all state machines, counters and registers are cleared and set to their defined reset value. The H.110 controller is in the reset state and all H.110 I/O pins are tri-stated as long as the CT_RESET pin is asserted. (see "CT_RESET" on page 48) The RESET and CT_RESET pins don't control the boundary scan register and TAPcontroller. If the TRST pin is asserted the TAP-controller will go into the Test-Logic-Reset state and all boundary scan elements are bypassed. All outputs and I/O-pins are controlled by the core logic and are tristated according to the programmed functionality or the core reset condition (pin RESET). The hardware reset must be issued for a minimum of 1 s, for more details please refer to the chapter "Hardware Reset Timing" on Page 146.
3.7.2
Software Reset
The software reset is accomplished by setting the 'Set Software Reset' command in the CMD2 register. The software reset clears the complete device except the clocking unit and the temporary microprocessor registers (e.g. CMD1). The software reset can be deactivated with the 'Set Software Reset' command. During software reset the microprocessor interface doesn't accept any other commands for a minimum of 1 s.

Local Bus Interface (PCM)

PCM Interface Configurations
The PFS Frame Sync is a 8 kHz signal and delimiting the frame. This input signal is used by the SWITI to determine the start of a frame. A frame is divided into 8-bit wide time-slots. The amount of time-slots within a frame depends on the selected data rate of PDC which can be 2.048 Mbit/s, 4.096 Mbit/s, 8.192 Mbit/s, 16.384 Mbit/s. The PFS input has a Schmitt-Trigger characteristic. The PDC Data Clock input supply the SWITI with a data clock. It can be operated with 2.048 MHz, 4.096 MHz, 8.192 MHz, or 16.384 MHz data rate clock depending on the selected highest data mode. The PDC clock signal must be equal or higher as the highest data rate. The PDC input has a Schmitt-Trigger characteristic. A clock slave must receive PFS and PDC whereas a clock master drives these signals. To enable or disable the signals for the clock master the command 'PCM Clock Input/ Output Selection' must be issued. The time-slots are transmitted and received via 16 input and 16 output lines (IN[15:0], OUT[15:0]). The input lines have a Schmitt-Trigger characteristic. The output lines have tristate outputs with push-pull characteristic. For every time-slot not participating to a connection the output is high impedance. With the special command "Local Bus (PCM) Standby" in the CMD2 register it is possible to set all PCM lines in a high impedance state during the normal operation mode. All PCM lines are in high impedance state after the reset process and must be enabled with the "Local Bus (PCM) Standby" command. All lines which are not participating on a switching operation are in high impedance state and the time-slot information on the input lines are discarded automatically.

PCM Bit Shifting
For each PCM input line the offset of time-slot zero can be adjusted in a range from 0 to 7 bit in half clock resolution before or after the PFS rising edge. For all output lines the offset of time-slot zero can be adjusted in a range from 0 to 7 bit in half clock resolution after the PFS rising edge. The resolution depends on the selected data rate that means the resolution doesn't depend on the PDC signal. After the reset process the bit shift is disabled for all lines. That means the time-slot 0 starts with the rising edge of PFS. All input data will be sampled with falling edge of the selected data rate and the output data are valid with the rising edge of the selected data rate.

CT_C8(A/B) and CT_FRAME(A/B)
The functional timing relationship of the CT Bus clocks can CT_FRAME can be found in the chapter "H-Bus and PCM (Local Bus) Frame Structure" on page 132. The CT_FRAME is a 8 kHz signal and delimiting the frame. The negative pulse, nominally 122 ns wide marks the beginning of the first bit of the first time-slot. The CT_C8 is the 8.192 MHz bit clock. The duty cycle of this signal is nominally 50%. A H.1x0 slave must receive CT_C8 and CT_FRAME whereas a clock master drives these signals.
4.2.2
Dataports
There are 32 bidirectional pins available for accessing the H-bus. The frame structure is shown in Chapter 7.3. For every pin there is a tri-state controller. The CT_EN signal enables the tri-state controller for the H.110 data lines. With the special command "PCM

and H.1x0 Standby" in the CMD2 register it is possible to set all H.1x0 lines in a high impedance state during the normal operation mode. All H.1x0 lines are in high impedance state after the reset process and must be enabled with the "PCM and H.1x0 Standby" command. All lines which are not participating on a switching operation are in high impedance state. The default data rate is 8.192 Mbit/s in accordance to the H.100/H.110 specification. With the configuration command register it is possible to select a individual data rate from 2.048 Mbit/s, 4.096 Mbit/s, and 8.192 Mbit/s in accordance to support the interoperabilitiy busses.
4.2.3
CT_EN
The CT_EN signal must be implemented in an identical manner to the implementation of the BD_SEL# signal as specified in the PICMG 2.1 CompactPCI Hot Swap specification by connecting CT_EN to a logic high (de-asserted) through a 1.2K 5% resistor or current source equivalent. The CT_EN signal indicates that a PCI board is fully seated. The H.110 interface logic is enabled if the CT_EN signal is active (logic low level enables all H.110 ports, PCM ports, and clock signals).
4.2.4
CT_RESET
The CT_RESET must be functionality and electrically equivalent to the CompactPCI signal RST#. The device must respond to the CT_RESET signal when it is asserted. All H.110 outputs and I/Os are high impedance until the CT_RESET is released as well as the related PCM outputs and I/Os. No clocking signal can influence the internal logic during the reset state. All internal state machines and counters are in a defined reset state after the CT_RESET signal is released and the connection memory is in the reset state. After the CT_RESET signal is released the device has to be configured with the configuration command register 1 and 2 (CMD1, CMD2). The RESET and CT_RESET (in conjunction with the mode pins M-Mode and H.110 Mode) signals are logical or connected.
4.2.5
H-MVIP C16 Signals
The differential signal is driven by the clock master and used to read and write bits on the serial data lines. Time-slot boundaries align with the falling edge of C16+. The C16 signal is differential. The SWITI doesn't have a integrated differential receiver/ transceiver with the required thresholds of the EIA standard RS-485. Nevertheless the differential C16+, C16- input signals are logical decoded to one internal /C16 signal if the SWITI is configured as clock slave. The C16- is the inverted C16+ signal if the SWITI shall generate the C16+, C16- signals.

Data Rate
The SWITI provides the programming of data rates on a per line basis for the local bus as well as for the H.100/H.110 bus. To support the H.100/H.110 bus and the interoperability bus systems all 32 H.100/H.110 data lines can operate with 2.048 MHz, 4.096 MHz, and 8.192 MHz independently. The following table shows the possible data rates for the different lines. Table 11

All local bus lines can operate with 2.048 MHz, 4.096 MHz, and 8.192 MHz independently and up to 24 local bus lines for the HTSI in M-mode or 8 local bus lines for the HTSI in H-mode can operate with 16.384 MHz as well. Having 16.384 Mbit/s in any of the PCM0..7 lines, the corresponding (PCM0..7 + 8) lines will be deactivated (tristate). Using all PCM0...7 lines with 16.384 Mbit/s all the PCM8...15 will be then deactivated. The input and output lines are independent of each other, i.e. for a given bus line the input and the output lines can be programmed with different data rates. For the HTSI the maximum aggregate data rate supported at the input and output bus lines is 393.216 Mbit/s, (e.g. 24 lines x 16.384 Mbit/s per line = 393.216 Mbit/s, as input and/or output).

If the GPIO port is not needed it can be used to provide a 16-bit P interface. The 16-bit mode is determined according to MODE16 input pin. MODE16 = '0' -> 8-bit interface MODE16 = '1' -> 16-bit interface This chapter describes how to configure the P interface to each mode.
4.4.1
Intel/Siemens or Motorola Mode
The Intel/Siemens or Motorola mode for the P interface can be configured during the hardware reset process in conjunction with the ALE pin. - ALE permanently driven to 'low' => Motorola mode - ALE permanently driven to 'high' => Intel/Siemens mode - Edge on ALE => Intel/Siemens multiplexed mode A falling or rising edge on ALE during the normal operation selects the multiplexed mode immediately. With the hardware reset and the tied ALE pin it is possible to return to the Motorola or Intel/Siemens mode.
4.4.2
De-multiplexed or Multiplexed Mode
In both modes, the A-bus and the D-bus are used in parallel. The A-bus should be connected to the LSBs of AD-bus, coming from the P, also in multiplexed mode.
The next figure describes the connection to the address and data buses in the different modes.
Note: Motorola mode is used only with de-multiplexed AD bus. Intel/Siemens mode may be used with both, multiplexed or de-multiplexed AD bus.

General Purpose Clocks
The SWITI provides 8 general purpose clock lines. With two independent commands in the CMD2 register the lines can be configured as frame group signals or individual clock signals. The last written command for a line is valid and controls the multiplexer.
4.6.1
Frame Group Outputs
Via 8 output lines it is possible to provide 8 different framing signals which are used for synchronization purpose. All signals have a period of 125 s. Their offset can be programmed individually within the PFS determined frame in a resolution of 61 ns (1/ 16.384 MHz). The default start point for the offset is the beginning of a frame (rising edge of PFS and the clock signal). The start point for the offset can be shifted for a half clock cycle, that means the second start point is determined with the rising edge of PFS and the next falling edge of the clock signal (as shown in Figure 24). The high time of the signal can also be programmed in steps of 61 ns. All frame signals can be controlled as high or low active.

GPCLK as Clock Outputs
All 8 GPCLK lines can be configured as individual clock outputs with 8 kHz, 2.048 MHz, 4.096 MHz, 8.192 MHz, 16.384 MHz and for test purposes with the internal frequency or the input frequency of the analog PLL (APLL). All clock signals are generated from the analog PLL output frequency which is the internal frequency. The quality of all output frequency signals depends on the quality of the selected input PLL frequency.

JTAG (Boundary Scan)
The SWITI provides a fully IEEE 1149.1 compatible boundary scan support consisting of: - a complete boundary scan chain - a Test Access Port controller (TAP controller) - five dedicated pins: TCK, TMS, TDI, TDO and a TRST to asynchronously reset the TAP controller - one 32-bit IDCODE register
4.7.1
Boundary Scan
All pins except power supply and crystal are included in the boundary scan. Depending on the pin functionality one (input), two (output, enable) or three (input, output, enable) boundary scan cells are provided. The maximum clock rate at pin TCK is 10 MHz.
4.7.2
Test-Access-Port (TAP)
The following signal pins allow the boundary scan test logic to be accessed: - TCK - Test Clock input to which a central BSc test clock is applied. This BSc test clock is independent of the system clock. Clock phases are derived from this clock for test sequence control. - TMS - Test Mode Select control input for which the desired status changes at the TAP controller by applying a certain level (0/1) caused by the rising edge of TCK. - TDI - Test Data Input whose data is inserted into the test logic with the rising edge of the TCK. - TDO - Test Data Output with tristate capability which is only active during the SHIFT-IR and SHIFT-DR controller state, and whose data is driven with the falling edge of TCK.

4.7.3
TAP Controller
The Test Access Port (TAP) controller implements the state machine defined in the JTAG standard IEEE 1149.1. Transitions on the pin TMS cause the TAP controller to perform a state change. The possible instructions are listed in the following table. Table 14 Code 0000 0001 0100 0101 0110 0111 1111 TAP Controller Instructions Instruction EXTEST IDCODE HIGHZ INTEST CLAMP BYPASS Function External testing Reading ID code High impedance state of all boundary scan outputs Internal testing Reading outputs Bypass operation
SAMPLE/PRELOAD Snap-shot testing
The instruction length is four bit. EXTEST is used to verify the board interconnections. When the TAP controller is in the state "update DR", all output pins are updated with the falling edge of TCK. When it has entered state "capture DR" the levels of all input pins are latched with the rising edge of TCK. The in/out shifting of the scan vectors is typically done using the instruction SAMPLE/PRELOAD. INTEST supports internal chip testing. When the TAP controller is in the state "update DR", all inputs are updated internally with the falling edge of TCK. When it has entered state "capture DR" the levels of all outputs are latched with the rising edge of TCK. The in/out shifting of the scan vectors is typically done using the instruction SAMPLE/PRELOAD. SAMPLE/PRELOAD The SAMPLE/PRELOAD instruction enables all signal pins (inputs and outputs) to be sampled during operation (SAMPLE) and the result to be shifted out through the shift BSc register. The function of the internal logic is not influenced by this instruction. While shifting out, the BSc cells can be serially loaded at the same time with defined values through TDI (PRELOAD). The SAMPLE/PRELOAD instruction selects the boundary scan register in normal mode. In state CAPTURE-DR data is loaded into the boundary scan register with the rising edge of TCK. In state UPDATE-DR the contents of the boundary scan register are written into the second register stage of the boundary scan register. This data becomes effective at the outputs only if an instruction has been activated that sets the BSc register to test mode: e.g. EXTEST or CLAMP.

Description of Interfaces
The 32-bit identification register is serially read out via TDO. It contains the version number (4 bits), the device code (16 bits) and the manufacturer code (11 bits). The LSB is fixed to '1'..

The BSc register is in test mode. For the duration of the CLAMP instruction, the BYPASS register is selected so that a minimal shift path is created. During SHIFT-DR data can be shifted through the BYPASS register. The contents of the BSc register does not change during the UPDATE-DR state. HIGHZ The HIGHZ instruction disables all outputs if switched to high impedance state. The outputs are switched to high impedance in state UPDATE-IR. The outputs are redefined according to the next new instruction if another instruction has become active with UPDATE-IR. The selected test data register is the BYPASS register. BYPASS, a bit entering TDI is shifted to TDO after one TCK clock cycle, e.g. to skip testing of selected ICs on a printed circuit board.

Identification Code via P Read Access
The SWITI offers two possibilities to read the identification code. - via the JTAG port as described in Chapter 4.7 - or via the processor interface After a hardware reset the identification code is stored in the General Purpose Interrupt Register (GPI) and can be read via the processor interface. The high nibble is the version number and the low nibble is equal to the low nibble of the device code shown in Table 16. For the 8-bit P interface configuration the first write access to the General Purpose Mask Register (GPM) will reset the register GPI to 00H. If the P interface is configured as a 16-bit interface the IDCODE can always be read from the GPI register, that means the GPI register will not be reset. The IDCODE for the P read access is shown in Table 16. Table 16 IDCODE via P Read Access 8-Bit IDCODE (MSB..LSB) Version HTSI HTSI-L HTSI-XL 0010 0010 0010 Device Code 1101 1110 1111
Note: The version number of the IDCODE register remains unchanged.

Fallback to Oscillator
If "Fallback to Oscillator" is enabled and a fallback has occurred, the corresponding failure is indicated in the IESTA1 and/or IESTA2 registers. For all clock failures, the PLL bit ("PLL Source Failure Indication", IESTA2 register) as well as the clock source related bit (in IESTA1 or IESTA2 register) will be set to "1". With the clock valid again the previously changed bits in IESTA1 and/or IESTA2 are set back to "0", the fallback must be disabled (CMD2=01H/11H) for a few cycles and enabled again thereafter. I2 APLLs parameters 0= 1= default start APLL with improved parameters
The command CMD2=41H or CMD2=51H to start the APLL with improved parameters must only be issued only once after Power Up 0010 = Parallel Mode (local bus only) Set the first 8 local bus input lines as 8 parallel input lines and set the first 8 local bus output lines as 8 parallel output lines.

Programming the Device
The register set consists of parameter registers (SPA, ITSA, SCA, DPA, OTSA, GI1..), command registers (CCMD, CMD1, CMD2) and status registers (ISTA1, IESTA1, IESTA2). Please note that some bits contained in the register ISTA1 (Interrupt Status Register 1) do not generate any interrupt, for more details see the paragraph Chapter 6.2. Before issuing a command the parameter registers have to be written accordingly. A connection command can only be issued if the connection command register is ready to be written to (see Figure 25). The connection command register status is shown with the RDY bit in the ISTA1 register. A detailed description for the read and write access to the command registers can be found in Chapter 6.1.

Read and Write Access
For the read and write access it is necessary to distinguish between a connection and configuration command. The connection command register is used to establish a connection (described in Chapter 6.11) and the configuration registers are used to configure the device, i.e. set the clock frequency. If the ISTA1:RDY bit is set the connection command register is ready to receive data from the P interface. If the parameter register and the connection command register are written the RDY bit will be reset from the internal controller. If the connection is established the internal controller will set the RDY bit and the connection command register is ready for the next write or read access. The ISTA1:RDY can be enabled to generate an interrupt to indicate that the device is ready to receive the data, otherwise the P must poll the ISTA1:RDY bit. The configuration command register works independent from the RDY bit. Note: There must be a recovery time period of 120 ns after every configuration command write access to the next write access (command or parameter register).

Interrupt Handling
The SWITI interrupt concept consists of four interrupt status register with their corresponding mask register. The five interrupt status register can be divided in one main register, and two error interrupt register, one general purpose interrupt register and one time-slot value register. Every secondary status register and the time-slot value register has a bit in the main register to indicate the set of an interrupt in the assigned error or general purpose register or to indicate a new value in the time-slot value register. The interrupt status register can be read via the microprocessor interface. The NFC and RDY will be set and reset from the internal controller. When an interrupt occurs one or more of the bit GPIO, TSA, ER2, or ER1 is set, then the assigned secondary interrupt status register or time-slot value register must be read first in order to check for the cause of the interrupt. After a secondary status register read access, the error status register and the corresponding bit in the Interrupt Status Register 1 (ISTA1) will be reset.

8-bit P Access Interrupt Structure
The IREQ output is level active. It stays active until all interrupt sources have been serviced. If a new status bit is set while an interrupt is being serviced (P read access), the IREQ pin stays active. For the duration of a write access to the INTM1 register the IREQ line is deactivated. When using an edge-triggered interrupt controller, it is thus recommended to rewrite the INTM1 register at the end of any interrupt service routine. APLL, STR, RDY and NFC Bits If the internal controller does set the RDY bit for the first time and the bit is not masked an interrupt will be generated. If the P reads the ISTA1 register the interrupt will be deactivated. The RDY bit is still active and can be reset from the internal controller. The NFC, STR and APLL bits are not set by any interrupt and therefore can not be masked. Setting these bit does not generate any interrupt. The NFC bit is set from the internal controller if no further connections can be established. The STR bit is set from the internal stream to stream controller if a stream to stream connection is configured. The APLL bit is set from the internal analog PLL controller if the PLL is locked.

PRELIMINARY Masking Interrupts
Programming the Device
If an interrupt is not masked (enabled) the IREQ pin will be active if one of the status bits in the interrupt status register is set. The mask bit prevents that the IREQ pin will be active if the status bit is set. The mask bits for the error status registers or general purpose interrupt register disables the interrupt indication for the interrupt status register. Only the interrupt status register can set the IREQ pin if the bit is not masked. Interrupt Structure for a 16-bit Microprocessor Access

Indirect Configuration Register Access
It is possible to read the current SWITI configuration with an indirect register access for analyze and test purpose. There are five commands in the CMD2 register which can be used to read the configuration. The clock generator output signal and external configuration for the SWITI can be read with the 'Read Configuration Command'. The four instruction bits select one possible configuration command. The current configuration is determined by the command written in the TSV register. The configuration information for every command can be found on page 58. The line configuration can be read with two commands 'Read PCM Line configuration' and 'Read H.1x0 Line configuration'. Before one of these commands will be issued the SPA or DPA register must be written with the port number. The configuration for the selected line is written in the TSV register by the internal controller. The interrupt handling is described in Chapter 6.2. The bit shift configuration can be read with the command 'Read Bit Shift Configuration' and the dataflow is the same as described above. With the command 'Read GPCLK Configuration' it is possible to read the configuration for every GPCLK line. If this command was written the configuration can be read from the TSV and CON register. The CON register is not interrupt controlled and will keep the last data after a microprocessor read access. To read the correct configuration data from the TSV register it is not allowed to use the command "Read Time-Slot Value" before the TSV register was read.

Initialization Procedure
After the reset process the PLL, H.1x0 interface, PCM interface, and some other signals need to be initialized. Since the SWITI offers the possibility to use two different external crystal/oscillator frequencies the command 'Set external frequency' must be used first to set the correct frequency and to set the correct value of the input frequency for the APLL. After approximately 750 s the APLL is locked and the APLL status bit is set and the next commands can be written.

H.1x0 Clocking Unit
If the HTSI in H-mode is used the the clock generator (PLL) for the H.1x0 interface must be programmed first. This chapter can be skipped for the M-mode. For the PLL synchronization please refer to Chapter 3.4.5 on page 36. They are three program sequences for the H.1x0 interface: - Program the H.1x0 fallback mechanism and PLL inputs for H.1x0 master or slave - Program all output clock signals for the master configuration - Program the frame signals for the slave configuration Program the PLL Source and H.1x0 Clock Fallback The program sequence for the PLL source programming and/or H.1x0 clock fallback must be finished with the command 'H.1x0 Master/Slave Selection' in the CMD1 register. Whenever the PLL source or the H.1x0 clock fallback was changed the H.1x0 Master/ Slave Selection' command must be programmed after this changes Example: A typical H.100 master or slave configuration is shown in Figure 29. Slave Configuration: - CT_C8_A as PLL input reference - Enable clock monitoring (CT_C8_A, CT_C8_B) - Enable automatic clock fallback from CT_C8_A to CT_C8_B H.100 Primary Master Configuration: - - - - NTWK_1 = 8 KHz as primary PLL reference CT_NETREF = 1.544 MHz as fallback PLL reference Enable automatic clock fallback for the primary master Enable automatic switch back to NTWK_1 if NTWK_1 returns

PCM Clocking Unit
If the HTSI in H-mode is used the H.1x0 clock generator must be programmed first.

This PCM clock configuration can be programmed with the special command 'PCM Input/Output Selection' in the Figure CMD1 register. For the PLL synchronization please refer to Chapter 3.4.5 on page 36. Example: HTSI in M-Mode as PCM clock master, PLL reference is NTWK_1 with 8 KHz and PDC is driven with 8.192 MHz and PFS is driven. - Write 00H to GI1 - Write 52H to CMD1 - Write B6H to CMD1 Example HTSI in M-Mode as PCM clock slave, PLL reference is PDC with 4.096 MHz. - Write 05H to GI1 - Write 22H to CMD1 - Write 26H to CMD1 (PDC = 4.096 MHz and PFS as input)

H.1x0/PCM Line Interface Standby Command
All H.1x0 and PCM lines are in a high impedance state after the reset process. If they are configured (data rate, bit shift) they can be enabled with the standby command. During the normal operation the PCM and H.1x0 lines can be enabled or disabled with the standby command. If the lines are disabled the device works internally like an active device.

Determining Clock Rates
The data rate range command is necessary to optimize the minimum delay feature. After the reset process the device assumes a bit rate of 2.048 Mbit/s for all PCM and H.1x0 lines. The command must be issued if other data rates are used. Example (8-bit P interface): 1. Specify that only 2.048 Mbit/s and 4.096 Mbit/s are used for following Set Bit Rate Command. - Write 38H to CMD2 2.

Performing Bit Shifting
The bit shift is performed on half-bit steps, not on a clock basis. It is a true bit shift, it means that with a data rate equals to the data clock frequency (e.g. 4.096 Mbit/s with 4.096 MHz data clock) programming a bit shift of 1-bit results on a shift of 1 clock period, and programming a shift of half-bit the result is a shift of half clock period. Running in double data clock rate (e.g. 4.096 Mbit/s with 8.192 MHz data clock), a bit shift of 1-bit results on a shift of 2 clock periods and a shift of half-bit will result on a shift of 1 clock period.

Read Time-Slot Value
By issuing this command the time-slot value appears in the register TSV after arriving and an interrupt will be caused and a new read time-slot value will be accepted. The command has to be issued for every read request. The current TSV data will be overwritten if the read time-slot command is issued. Example (8-bit P interface): Read time-slot 10 of local bus input line 3 - Write 03H to SPA - Write 0AH to ITSA - Write 0DH to CMD1 Example (16-bit P interface): - Write 0A03H to SA - Write 0DH to CMD1 Wrong Time-Slot and Time-Out In some case it could be happen that the P tries to read a wrong time-slot. A wrong timeslot is defined as a invalid time-slot number for the selected data rate, i.e. data rate = 2 MBit/s and selected time-slot is 58. If the P tries to read a wrong time-slot no interrupt would be generated and the controller doesn't accept any further commands. The SWITI has a integrated time-out counter to allow a new read time-slot command after the maximum of three frames.

Microprocessor Interface Timing
Microprocessor accesses of the SWITI are performed by an activation of the address and CS. - By driving the MODE16 pin 'low' the user selects the 8-bit microprocessor interface, by driving it 'high' - the 16-bit microprocessor interface. - By driving the ALE pin 'high' the user selects Intel/Infineon mode, by driving it 'low' Motorola mode. The pin is sampled during the hardware reset process. - In Intel/Infineon mode, a distinction is needed between working in multiplexed address/data bus mode and de-multiplexed address and data bus mode. In Motorola mode, only de-multiplexed busses are used. By driving the ALE pin 'high' during the normal operation the user selects the de-multiplexed mode, a falling or rising edge during the normal operation selects the multiplexed mode.
7.6.1
Infineon/Intel Timing in De-Multiplexed Mode
In this mode driving RD 'low' causes a read access, driving WR 'low' causes a write access. In de-multiplexed bus configuration, ALE must be driven `high'.

Note: The read/write recovery time (tRI and tWI) are required only for consecutive accesses to the microprocessor interface.
