6 cat5409 document no. 2010, rev. h preliminary information serial bus protocol the following defines the features of the 2-wire bus protocol: (1) data transfer may be initiated only when the bus is not busy. (2) during a data transfer, the data line must remain stable whenever the clock line is high. any changes in the data line while the clock is high will be interpreted as a start or stop condition. the device controlling the transfer is a master, typically a processor or controller, and the device being controlled is the slave. the master will always initiate data transfers and provide the clock for both transmit and receive operations. therefore, the cat5409 will be considered a slave device in all applications. start condition the start condition precedes all commands to the device, and is defined as a high to low transition of sda when scl is high. the cat5409 monitors the sda and scl lines and will not respond until this condition is met. stop condition a low to high transition of sda when scl is high determines the stop condition. all operations must end with a stop condition. device addressing the bus master begins a transmission by sending a start condition. the master then sends the address of the particular slave device it is requesting. the four most significant bits of the 8-bit slave address are fixed as 0101 for the cat5409 (see figure 5). the next four significant bits (a3, a2, a1, a0) are the device address bits and define which device the master is accessing. up to sixteen devices may be individually addressed by the system. typically, +5v and ground are hard-wired to these pins to establish the device's address. after the master sends a start condition and the slave address byte, the cat5409 monitors the bus and responds with an acknowledge (on the sda line) when its address matches the transmitted slave address. acknowledge after a successful data transfer, each receiving device is required to generate an acknowledge. the acknowledging device pulls down the sda line during the ninth clock cycle, signaling that it received the 8 bits of data. the cat5409 responds with an acknowledge after receiving a start condition and its slave address. if the device has been selected along with a write operation, it responds with an acknowledge after receiving each 8-bit byte. when the cat5409 is in a read mode it transmits 8 bits of data, releases the sda line, and monitors the line for an acknowledge. once it receives this acknowledge, the cat5409 will continue to transmit data. if no acknowledge is sent by the master, the device terminates data transmission and waits for a stop condition. acknowledge 1 start scl from master 89 data output from transmitter data output from receiver figure 4. acknowledge timing 5020 fhd f06
7 cat5409 document no. 2010, rev. h preliminary information write operations in the write mode, the master device sends the start condition and the slave address information to the slave device. after the slave generates an acknowledge, the master sends the instruction byte that defines the requested operation of cat5409. the instruction byte consist of a four-bit opcode followed by two register selection bits and two pot selection bits. after receiving another acknowledge from the slave, the master device transmits the data to be written into the selected register. the cat5409 acknowledges once more and the master generates the stop condition, at which time if a non- volatile data register is being selected, the device begins an internal programming cycle to non-volatile memory. while this internal cycle is in progress, the device will not respond to any request from the master device. acknowledge polling the disabling of the inputs can be used to take advantage of the typical write cycle time. once the stop condition is issued to indicate the end of the host's write operation, the cat5409 initiates the internal write cycle. ack polling can be initiated immediately. this involves issuing the start condition followed by the slave address. if the cat5409 is still busy with the write operation, no ack will be returned. if the cat5409 has completed the write operation, an ack will be returned and the host can then proceed with the next instruction operation. write protection the write protection feature allows the user to protect against inadvertent programming of the non-volatile data registers. if the wp pin is tied to low, the data registers are protected and become read only. the cat5409 will accept both slave addresses and instructions, but the data registers are protected from programming by the device s failure to send an acknowledge after data is received. figure 6. write timing 5020 fhd f08 s a c k a c k dr1 wcrdata s t o p p bus activity: master sda line s t a r t a c k slave/dpp address instruction byte fixed variable op code register address pot1 wcr address figure 5. slave address bits 0 1 0 1 a3a2a1a0 cat5409 * a0, a1, a2 and a3 correspond to pin a0, a1, a2 and a3 of the device. ** a0, a1, a2 and a3 must compare to its corresponding hard wired input pins.
8 cat5409 document no. 2010, rev. h preliminary information instruction and register description instructions slave address byte the first byte sent to the cat5409 from the master/ processor is called the slave/dpp address byte. the most significant four bits of the slave address are a device type identifier. these bits for the cat5409 are fixed at 0101[b] (refer to table 1). the next four bits, a3 - a0, are the internal slave address and must match the physical device address which is defined by the state of the a3 - a0 input pins for the cat5409 to successfully continue the command sequence. only the device which slave address matches the incoming device address sent by the master executes the instruction. the a3 - a0 inputs can be actively driven by cmos input signals or tied to v cc or v ss . instruction byte the next byte sent to the cat5409 contains the instruction and register pointer information. the four most significant bits used provide the instruction opcode i [3:0]. the r1 and r0 bits point to one of the four data registers of each associated potentiometer. the least two significant bits point to one of four wiper control registers. the format is shown in table 2. table 1. identification byte format id3 id2 id1 id0 a3 a2 a1 a0 0101 (msb) (lsb) device type identifier slave address table 2. instruction byte format i3 i2 i1 i0 r1 r0 p1 p0 (msb) (lsb) instruction data register wcr/pot selection opcode selection data register selected r1 r0 dr0 0 0 dr1 0 1 dr2 1 0 dr3 1 1 data register selection
9 cat5409 document no. 2010, rev. h preliminary information table 3. instruction set wiper control and data registers wiper control register (wcr) the cat5409 contains four 6-bit wiper control registers, one for each potentiometer. the wiper control register output is decoded to select one of 64 switches along its resistor array. the contents of the wcr can be altered in four ways: it may be written by the host via write wiper control register instruction; it may be written by transferring the contents of one of four associated data registers via the xfr data register instruction, it can be modified one step at a time by the increment/decrement instruction (see instruction section for more details). finally, it is loaded with the content of its data register zero (dr0) upon power-up. the wiper control register is a volatile register that loses its contents when the cat5409 is powered-down. although the register is automatically loaded with the value in dr0 upon power-up, this may be different from the value present at power-down. data registers (dr) each potentiometer has four 6-bit non-volatile data registers. these can be read or written directly by the host. data can also be transferred between any of the four data registers and the associated wiper control register. any data changes in one of the data registers is a non-volatile operation and will take a maximum of 5ms. if the application does not require storage of multiple settings for the potentiometer, the data registers can be used as standard memory locations for system parameters or user preference data. instructions four of the nine instructions are three bytes in length. these instructions are: read wiper control register - read the current wiper position of the selected potentiometer in the wcr write wiper control register - change current wiper position in the wcr of the selected potentiometer read data register - read the contents of the selected data register write data register - write a new value to the selected data register the basic sequence of the three byte instructions is illustrated in figure 8. these three-byte instructions note: 1/0 = data is one or zero instruction instruction set operation i3 i2 i1 i0 r1 r0 wcr1/ p1 read wiper control register 1001 00 1/0 1/0 read the contents of the wiper control register pointed to by p1-p0 write wiper control register 1010 00 1/0 1/0write new value to the wiper control register pointed to by p1-p0 read data register 10111/01/01/0 1/0 read the contents of the data register pointed to by p1-p0 and r1-r0 write data register 11001/01/01/0 1/0write new value to the data register pointed to by p1-p0 and r1-r0 xfr data register to wiper control register 11011/01/01/0 1/0 transfer the contents of the data register pointed to by p1-p0 and r1-r0 to its associated wi per control register xfr wiper control register to data register 11101/01/01/0 1/0 transfer the contents of the wiper control register pointed to by p1-p0 to the data register pointed to by r1-r0 global xfr data registers to wiper control registers 00011/01/0 0 0 transfer the contents of the data registers pointed to by r1-r0 of all four pots to their respective wiper control register s global xfr wiper control registers to data register 10001/01/0 0 0 transfer the contents of both wiper control registers to their respective data registers pointed to by r1-r0 of all four pots increment/decrement wiper control register 0010 00 1/0 1/0 enable increment/decrement of the control latch poi nted to by p1-p0 wcr0/ p0
10 cat5409 document no. 2010, rev. h preliminary information exchange data between the wcr and one of the data registers. the wcr controls the position of the wiper. the response of the wiper to this action will be delayed by t wrl . a transfer from the wcr (current wiper position), to a data register is a write to non-volatile memory and takes a minimum of t wr to complete. the transfer can occur between one of the four potentiometers and one of its associated registers; or the transfer can occur between all potentiometers and one associated register. four instructions require a two-byte sequence to complete, as illustrated in figure 7. these instructions transfer data between the host/processor and the cat5409; either between the host and one of the data registers or directly between the host and the wiper control register. these instructions are: xfr data register to wiper control register this transfers the contents of one specified data register to the associated wiper control register. xfr wiper control register to data register this transfers the contents of the specified wiper control register to the specified associated data register. global xfr data register to wiper control register this transfers the contents of all specified data registers to the associated wiper control registers. global xfr wiper counter register to data register this transfers the contents of all wiper control registers to the specified associated data registers. increment/decrement command the final command is increment/decrement (figure 5 and 9). the increment/decrement command is different from the other commands. once the command is issued and the cat5409 has responded with an acknowledge, the master can clock the selected wiper up and/or down in one segment steps; thereby providing a fine tuning capability to the host. for each scl clock pulse (t high ) while sda is high, the selected wiper will move one resistor segment towards the r h terminal. similarly, for each scl clock pulse while sda is low, the selected wiper will move one resistor segment towards the r l terminal. see instructions format for more detail. figure 7. two-byte instruction sequence figure 8. three-byte instruction sequence figure 9. increment/decrement instruction sequence s t a r t 0101 a2 a0 a c k i2 i1 i0 r1 r0 p1 a c k sda s t o p id3 id2 id1 id0 p0 device id internal instruction opcode address register address pot/wcr address a1 a3 i3 i3 i2 i1 i0 id3 id2 id1 id0 device id internal instruction opcode address data register address pot/wcr address s t a r t 0101 a2 a1 a0 a c k r0 p1 p0 a c k sda s t o p i n c 1 i n c 2 i n c n d e c 1 d e c n r1 a3 i3 i2 i1 i0 r1 r0 id3 id2 id1 id0 device id internal instruction opcode address data register address pot/wcr address wcr[7:0] or data register d[7:0] s t a r t 0 101 a2 a1 a0 a c k p1 p0 a c k sda s t o p a c k d7 d6 d5 d4 d3 d2 d1 d0 a3
