6.0 FUNCTIONAL DESCRIPTIONS
HOST INTERFACE The command and response of the MX93030A is represented by an 16-bit code. The MX93030A supports the synchronous serial and 8-bit parallel communication protocol with the host. 8-bit parallel: The host can access PHDB(7:0) pins in two accesses selected by PHILO pin. When the host sets PHILO to low the host writes the low byte of the command to the register of DSP, and DSP does nothing but latches the data; While host sets PHILO to high, the host writes the high byte of the command to the register and then DSP executes the command. PACKB\ is defaultly set to high. After finished the command, DSP returns the response by set the PACKB\ low to indicate host. When host has read the high byte of reponse, PACKB\ will be reset to high. Note that the host accesses this register by low byte first,and then high byte.

- 64K x 16 - 128K x 8, 128K x 16 - 256K x 4, 256K x 8, 256K x 16 - 512K x 2, 512K x 4, 512K x 8, 512K x 12, 512K x 16 - 1M x 1, 1M x 2, 1M x 4, 1M x 8, 1M x 12, 1M x 16 - 2M x 1, 2M x 2, 2M x 3, 2M x 4, 2M x 8, 2M x 12, 2M x 16 - 4M x 1, 4M x 2, 4M x 3, 4M x 4, 4M x 8, 4M x 12, 4M x 16 - 8M x 1, 8M x 2, 8M x 3, 8M x 4, 8M x 8, 8M x 12, 8M x 16 - 16M x 1, 16M x 2, 16M x 3, 16M x 4, 16M x 8, 16M x 12, 16M x 16
the HOST. The HOST can stop recording, and delete the last n*400 or n*200 ms from the memory using a Record Stop command with assigned Tail Cut Factor. The MX93030A can generate a desired tone during recording voice message, which allows the application such as two-way recording. During recording, Record Pause function is provided. The recording voice signal, received through the CODEC input, is transmitted back to the CODEC output by the MX93030A. This Loop-Back function can be disabled by the host in the personal mail command.
Announcement (ANNC) Record
The MX93030A provides flexible recording ways for outgoing message. The HOST can select to delete the old ANNC before a new one is recorded or to abort the new ANNC record without losing the old ANNC.
2. 4M bits & larger density ARAM specifications : - ARAM speed is not less than 120 ns. - ARAM refresh use CAS-BEFORE-RAS mode. - The number of column address line is greater than or equal to 4. - There are no failed bit in first 16 rows. - ARAM is separated to 16384 clusters, one bit of one cluster being failed will be a bad cluster. - DC/AC characteristics are the same as those of standard DRAM. - Maximum input/output leakage current is 2 uA. - Maximum stand-by current is 2mA.
New/Old Message
For the HOST to manipulate incoming messages more handily, the MX93030A keeps an internal record of the ICM to identify the new/old status of messages. Before playback, the status of ICM is considered as "new". All incoming messages that have been played could change their status to "old" by issuing Real Del bit on DELETE command. After Real Del is issued, all new/ old ICM Msg IDs will be rearranged. The functions, Playnew or Delete-all-old messages, are provided by the MX93030A in the command set.
Voice Message Recording and Storage
The MX93030A provides a high quality 4.8 kbps speech compression technique with silence compression to permit over 14 minutes of speech storage in each 4M bit of memory device. The chip supports up to 127 variable length incoming and outgoing messages that are labeled as Msg ID 1 to 127. Although ICM could range from Msg 1 to 127, Msg IDs 127 to 121 are the only places for outgoing messages (OGM) storage so that the recovery of old OGM are easier to maintain. The Msg IDs of incoming messages are labeled chronologically and rearranged automatically after recording or deleting. ICM with Msg ID 1 is the oldest recorded incoming message. During recording, the MX93030A also monitors the telephone line signal to detect the presence of DTMF, Call progress Tone and Continuous Tone and responses to
Message Playback
Random access for playback of any new message or message with specified Msg ID is supported by the MX93030A. During playback, the MX93030A also monitors the telephone line signals, and Play Pause function is provided. The MX93030A is able to fast-forward the playback of a recorded message, and the playing speed will be up to 33%.

MX93030A
Message Deletion
The MX93030A provides two ways to delete recorded ICMs. One is the two-step method -- the combination of Del Mark on Play command and Real Del on Delete command, and the other is the immediate method -Delete command. The two-step method enables the HOST to handle the deletion more flexibly, while the immediate method deletes a specified message directly.
Call Progress Tone Detection
The MX93030A supports the detection of call progress tones within the band of 300-640 Hz for the incoming telephone line signal. The tone detector is implemented with a bandpass filter. Indication of the presence of call progress tones is responded to the HOST, and could be used to terminate recording.
Near End Echo Cancellation Voice Prompt
For high-quality Voice Prompt playback, the MX93030A utilizes the built-in speech decoder and an internal ROM or/and external EPROM/ROM to store the vocabulary. The chip also supports up to a 62-Kword external EPROM/ROM that allows minimum 3.44 minutes of voice prompt storage. The combination of internal (lower part) and external (upper part) voice prompt is allowed. The vocabulary supports up to 255 phrases. Given a phrase number in the Voice Prompt command from the control program, the MX93030A outputs the corresponding utterances to the Codec interface. The starting address of voice prompt data could be located at data address 0800hex or program address 8000hex. During playback of the voice prompt, the MX93030A monitors the telephone line signals. The MX93030A implements a near end echo canceller in software to enhance the detection of DTMF and Call Progress Tone during Playback and Voice Prompt mode.
Vox Detection (Digital Voice Activated Recording)
The speech detection is implemented in the DAM chip to indicate whether the recording signal level is above the Vox threshold. If the HOST sets the Vox Record bit on Initial command, the recording of the speech would start when the voice activity is detected. The HOST has to set Vox threshold by issuing command mode 13. Hexadecimal numbers for Vox threshold are listed in Table 6.
Query and Report
The MX93030A is capable of reporting to the HOST about the query of the current status, such as the number of recorded messages, the number of new messages, the number of old messages, the available recording time, the status of recorded message.
Time Keeping
There is a timer clock in the MX93030A. The HOST can issue Set Time and Get Time commands to get time services. The clock also supports system to stamp time to the recorded incoming messages.
Personal Mail
The MX93030A supports up to 8 mailboxes that may be used for personal mail application. Each mailbox has its own ICM/MEMO Msg ID. Before recording or playing messages, the HOST should set the corresponding mailbox number first with Personal Mail command.
DTMF Detection
For remote control operation of the answering machine, the MX93030A monitors the incoming telephone line signal to detect the presence of DTMF signal.
Speed Dial Telephone Number Storage Tone Generation
Up to double tones can be generated by the MX93030A. The levels and frequencies are programmable by the HOST. The MX93030A can store up to 63 sets for telephone number storage. For the AFLASH memory, each set supports 13bytes. For ARAM memory, each set supports 14bytes. These memory could be also used for other special purpose.

Caller ID
The MX93030A provides a caller ID mode command to demodulate the FSK data transmitted from the central office to the subscriber. This FSK data should conform to 1200 Baud Bell 202 protocol and may contain the date, time and the phone number and name of calling party. The MX93030A offers two kinds of output on decoding FSK data. One is the cooked data mode, which presents the valid sequence output to be calling name, phone number, time and date. The other is the raw data mode, which output the data streams including the header information, alternate 1 and 0, and mark, which precedes the calling information. All the cooked data are buffered in internal memory of MX93030A; while the raw data should be read out by the HOST on real time basis. In cooked data mode, the MX93030A decodes the input and interprets the frame data according to the requirements of Bellcore CLASS feature. The MX93030A reflects the related flags on response word to show the channel signal status and the validity of current FSK data. The carrier_detected flag (CD) indicates a valid carrier is present on the line and may be used for a signaling of the starting or ending of FSK bit streams. The ERR flag shows the decoded data is not correct, which is caused of wrong checksum detected or buffer overflowed. The data_ready flag (DR) is set when a FSK data is output. The end_of_frame flag (EOF) shows a complete frame of FSK cooked data is read out.
7.0 OPERATION DESCRIPTION
INITIAL PROCEDURE
When the system is powered up, the input PWD\ (pin 15) signal should go high followed by the input RST\ (pin 96) pulse that should be low at least 10 ms long. After reset, the MX93030A identifies itself to be in cold or warm stage by comparing the system checksum and responds to each situation as follows: 1.The system checksum remains unchanged -- warm start, which means messages in ARAM and data in internal SRAM are kept correct by backup batteries during power down. In this case, the MX93030A restores all the previous conditions and system parameters. 2. The system checksum is changed -- cold start, which means the messages and data have been lost before the system is powered up. Then, the MX93030A will initialize all the system parameters to their default values. After completing the above system initialization, the MX93030A is ready and indicates the HOST by setting PACK\ or SO low. The HOST should poll the indication to read the response first, then send the vocabulary configuration command to MX93030A and check the response status. If needed, the HOST should set the parameter by sending the relative command.
Power Down
With the power of backup batteries, the MX93030A is capable of keeping messages and data stored in the ARAM during power failure. In power down mode, the MX93030A will run at a lower clock rate to reduce power consumption and keep refreshing the ARAM.

MODES OF OPERATION
After reset, the MX93030A is normally in Idle mode and keeps polling command from the HOST. When a command is issued by HOST, the system will enter the new mode. For some of the mode, the system will return to Idle mode after operation is completed. While other modes, Record, Playback, Line Monitor, Voice Prompt, and Telephone numbers, require Stop or Idle command to return to Idle mode. The MX93030A supports 16 modes of operation, that are listed as follows: Command 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Mode Name Idle Record Play Message status Tone Generation Line Monitor Delete Message Set Time/OPT0-7/Voice Prompt/ Silence Threshold Get TIME/OPT/IPT Initial & Test Memory Get Record Message status Voice Prompt Voice Activity Personal Mail Telephone Number Caller ID
DESCRIPTION OF MODES OF OPERATION
RECORD
When Record command is received from the HOST, the MX93030A performs speech compression, stores the message and monitors telephone line. If the Vox Record bit had been set to 1 on Initial & Test command, recording of the speech will start upon the voice activity detected, else the MX93030A starts recording immediately after Record command is received. Clearing Marked Record (bit 8-10) to 0, if it is recording ICM. When recording OGM, the HOST should set Marked Record (bit 8-10) to desired number other than 0 as OGM ID. Setting bit 5 (Annc Del) to 1 on Initial & Test command, the HOST can choose to delete the old announcement before a new one is recorded. But in this case, Mark Fail(bit 11) on Record Command is inhibited. If that bit is cleared to 0, the new announcement recording can be aborted without losing the old announcement by issuing Mark Fail (bit 11) on Record command. During recording, the HOST can pause the recording by setting Pause (bit 7) to 1 and resume recording by clearing that bit. Line Monitoring will continue during pause. The HOST can stop recording by setting Stop (bit 6) to 1, and delete the last n*400 ms or n*200 ms from the memory by using a Record command with assigned Tail Cut Factor (bit 0-5). While system memory is full, the MX93030A will stop message recording, show the status in response word (bit 7, Mfull), not perform line monitoring, but still remain in Record mode. During Record mode, the HOST can instruct the MX93030A to generate a tone by issuing the Tone generation command. Setting Stop bit on Tone Generation command or Record command will stop tone generating. In recording, all commands will be ignored except Idle Record, Get time/OPT/IPT, Set time/OPT0-7/Voice Prompt/Silence threshold and Tone Generation. The MX93030A will terminate Record mode and return to Idle mode when Stop bit or mark fail bit on Record command is set to 1 or Idle command is issued.

INDEX
MX93030A
Note: The MX93030A supports up to 127 incoming and outgoing messages recording which are labeled as Msg ID 1-127. The Msg IDs of incoming message are labeled chronologically and rearranged automatically after recording. Although ICM could range from Msg 1 to 127, Msg IDs 127 to 121 are the only place for outgoing message storage. So, it is strongly suggested that the HOST should keep an upper bound of the number of ICM. (For example, upper bound of ICM=127 - maximum OGM number that will be applied in user's specification.) If the power supply of MX93030A is off, the current recording message will be discarded. In playing, all commands will be ignored except Idle Play, Get time/OPT/IPT, Set time/OPT0-7/Voice prompt/Silence threshold and Tone Generation. The MX93030A will terminate Play mode and return to Idle mode when Stop bit or Del Mark bit is set to 1 on Play command or Idle command is issued.
MESSAGE STATUS In this mode, there are four request codes for the HOST to get message information: 1.Get the number of recorded message (request code=0) 2.Get the number of new message (request code=1) 3.Get the number of old message (request code=2) 4.Get the available recording time with unit of second (request code=3). The result will be reported in the response word.
PLAY
When Play command is received from the HOST, the MX93030A performs message playback and line monitoring. The Msg ID (bit 0-6) is set by the HOST to specify which message to play. To playback new message (nonplayed one), set Play New (bit 10) to 1, then the MX93030A will search to play the non_played message with specified Msg ID. During playing, the HOST can pause playback by setting Pause (bit 8) to 1 and resume playing from the same point by clearing that bit. Line Monitoring will continue during pause. To fast playback a recorded message, set Fast Play (bit 11) to 1 and the playing speed will be up to 33%. To delete and stop the playing message, the HOST can set Del Mark (bit 7) on play command. After being tagged a Del Mark, the marked message is not really deleted until a Real Del (bit 8) on Delete command is issued. The Real Del command not only deletes the messages that have been tagged a Del Mark but also changes the status of those ICMs that have been played to old. The ICMs that have not been played before are regarded as "new" . After Real Del is issued, all new/old ICM Msg IDs will be rearranged. For the HOST, it is used to issuing the Real Del after the user terminates the manner of playback. The response word contains the information of tones detected from the line, playing time spent (bit 8-15) and End of play flag (bit 6), which indicates the end of the current message. When the Play_End bit is 1, the MX93030A stops playback but still remains in Play mode. The MX93030A will respond to the Play_End flag if the HOST wants to play invalid or nonexistent messages.
TONE GENERATOR
In this mode, up to double tones can be generated by the MX93030A. By the setting of CODE the frequency may be programmable or default. CODE 000 001 010 011 100 101 110 111 FREQENCY PROGRAMMABLE F1/F2 800 HZ 900 HZ 1000 HZ 1200 HZ 1500 HZ 1800 HZ 2100 HZ
Programmable frequency : CODE(BIT8-10) on command is 000. The tone levels and frequencies are programmable and controlled by the HOST. All the parameters are defined by the sequence of three Tone Generation commands. The first command defines the output gains in bit 0-3 for the 1st tone, and bit 4-7 for the 2nd tone. Each tone can be programmed from 0 dB (gain code 0000) to -28 dB (gain code 1110) with 2 dB resolution. The frequencies are defined in the second and third commands with the following relationship: frequency code=desired frequency (Hz) *8.19 f(n)=32767*cos (2*pi*f_code*n/(8000*8.19))

MX93030A
where f_code is the input frequency code, n is sequence index and 8000 is the sampling rate For single tone, Codec outputs the signal s(n): s(n)=gain*f(n) For dual tone, Codec outputs the signal s(n): s(n)=0.5*(gain1*f1(n)+gain2*f2(n)) To generate a single tone, the gain code of the other tone should be set to 1111. The MX93030A starts tone generation only after receiving the third command. Default frequency : CODE (bit8-10) on command is not 000. The output frequency is specified by the code. The MX93030A starts tone generation after receiveing the first command which defines the gain in bit 0-3. The MX93030A will terminate tone generation when Start/Stop bit is set to 0 on Tone Generation command.
DELETE MESSAGE
This mode provides an immediate way to delete messages as follows: 1.To delete a specified message, set its Msg ID in bit 06 and clear bit 11, 10, 8 and 7 to zero. 2.To delete all old ICM, set Del_All_Old (bit 7) to 1 and clear bit11, 8 to zero. (Bit 0-6 is ignored) 3.To delete a specified new ICM, set Del_New_Msg (bit 10) to 1, give the New Msg ID in bit 0-6, clear bit 11,8 and 7 to zero. 4.To erase the Del Mark from a specified ICM (Del Mark is a tag set on Play command for real deletion), set Del_Mark_Clr (bit 11) to 1, give the Msg ID in bit 0-6 and clear bit 10, 8 and 7 to zero. 5.To delete message that has Del Mark tag, set Real Del (bit8) to 1 and clear bit 11,10 and 7 to zero. If the HOST deletes invalid or nonexistent messages, an error flag will show on bit 0 of the response word.
LINE MONITOR
In this mode the MX93030A monitors the telephone line signal for the detection of DTMF, Call Progress Tone, Vox, and/or Continuous Tone. The MX93030A keeps monitoring the line until Stop bit is set to 1. The MX93030A returns to the HOST a response word that reflects the flag of Call Progress Tone, Vox, Continuous Tone and the index of DTMF signal that has been detected: INDEX 0 1 2 3 4 5 6 7 8 9 A B C DTMF CODE No Tone 1 2 3 4 5 6 7 8 9 * 0 #
SET TIME/OPT0-7/VOICE PROMPT/SILENCE THRESHOLD
In this mode the HOST can set the current time, output port7-0, voice configuration and silence threshold. The time information includes second, minute, hour and week. The timer in the MX93030A will be used to stamp time and day to the recorded message. 1.To set second, put the data in bit 0-7 and use request code(bit 8-11) 0000. 2.To set minute, put the data in bit 0-7 and use request code(bit 8-11) 0001. 3.To set hour, put the data in bit 0-7 and use request code(bit 8-11) 0010. 4.To set week, put the data in bit 0-7 and use request code(bit 8-11) 0011. 5.To set OPT 0-7, put the output data in bit 0-7 and use request code(bit 8-11) 0100. 6.To set link index, put the data in bit 0-7 and use request code (bit8-11) 0101.
The MX93030A will terminate Line Monitor mode and return to Idle mode when Stop bit it set to 1 on Line Monitor command, or Idle command is issued.

7.To configure voice prompt, put data in bit0-1 and use request code(bit 8-11) 0110. The responded status includes internal voice prompt test result, external voice prompt test result, external voice prompt location and data unit. 8.To set silence threshold, use request code (bit 8-11) 0111. 9.To set MX93000, put the control data in bit 0-7, specify register in bit 8-10 and set bit 11 to 1. pre-defined specification, the MX93030A responds 1 in G/B status bit. It will take 37 seconds to do complete ARAM initialization or 7.6 seconds to do fast ARAM initialization. After initialization, all messages in the MEMORY are lost.
2.ARAM Pattern Check
The MX93030A allows the HOST to check the status of MEMORY by setting the Mem. Check (bit 1) on this command. By checking the patterns, produced in Initialization MEMORY mode and stored in MEMORY, the MX93030A can identify the current MEMORY status to be good or bad.
GET TIME/OPT/IPT
In this mode the HOST can get the current time from the internal timer clock of the MX93030A. The time information includes second, minute, hour and week. 1.To get second, use request code (bit 8-11) 0000. 2.To get minute, use request code (bit 8-11) 0001.

The HOST should set Line-On (bit 3) to 1 if the system is logged in from telephone line; and clear that bit to 0 if in local keypad operation. Failing to set this bit properly will degrade the performance of echo cancellation.
4. Vox On/Off Record
3.To get hour, use request code (bit 8-11) 0010. 4.To get week, use request code (bit 8-11) 0011. 5.To get OPT 0-15, use request code (bit 8-11) 0100. 6.To get OPT 0-15, use request code (bit 8-11) 0101. 7.To get IPT 0-7, use request code (bit 8-11) 0110. The requested data will be reported in the response word. If the HOST turns on the Vox Record function (by setting bit 4 to one) on this command, speech recording will start upon the voice activity detected, else recording will start immediately after Record command is issued.
5.Announcememt Deletion
By setting bit 5 (Annc Del) to 1 on this command, the HOST can choose to delete the old announcement before recording a new one. If that bit is cleared to 0, the old announcement is not deleted until the new announcement recording is completed. With this option, the new announcement recording can be aborted without losing the old announcement by issuing Mark Fail (bit 11) on Record command.
INITIAL & TEST MEMORY
In this mode there are 6 functions for the HOST to define:
1.Momory Initialization
The HOST can initialize the ARAM/AFLASH by Mem. Init. (bit 0) to 1. This function is normally used after first power-up of the system. The HOST must send this command to the MX93030A in order to format MEMORY. The MX93030A performs MEMORY formatting to determine the MEMORY size (address space and bit width) and detect the good/bad memory unit of MEMORY. The response word reported to the HOST contains the information of MEMORY bit size (bit 0-3), MEMORY address size (bit 4-7), MEMORY good/bad status (bit 8) and MEMORY good rate (bit9-15). If the examination in the initialization shows that the MEMORY quality meets the
13
6.Condition of message change to old When the Real Del (bit 8) on Delete command is issued, the ICMs could be changed their status to old under the following conditions. a.New/Old sel (bit 6) is set to 1 and the ICMs have been ever played. b.New/Old sel (bit 6) is cleared to 0 and the ICMs have been played end.
INDEX
MX93030A
GET RECORD MESSAGE In this mode, there are ten request codes for the HOST to get the related information about a specified message. Given the Msg ID (bit 0-6) and New_Msg flag (bit 7), the MX93030A can provide message recording time, recording length, attribute and Del Mark status according to the Request Code (bit 8-11) as follows: 1.Get the recording time -- second. (Request Code = 0000) 2.Get the recording time -- minute. (Request Code = 0001) 3.Get the recording time -- hour. (Request Code = 0010) 4.Get the recording time -- week. (Request Code = 0011) 5.Get the recording length (sec). (Request Code = 0100)
VOICE PROMPT
In this mode the MX93030A plays back a speech segment that the corresponding phrase number is given in command bit 0-7. Up to 255 speech segments, previously stored in an external ROM/EPROM,are provided by the MX93030A and pronounced using the speech decompression algorithm. The HOST can pause the playback by setting PS (bit 8) to 1 or resume from pause by clearing PS bit to 0. Fast forward playback of voice prompt is also provided by setting Fast Play (bit 11) to 1. During Voice Prompt mode, the MX93030A keeps monitoring the line signal and sends the results in response word to the HOST. The MX93030A will terminate Voice Prompt mode and return to Idle mode when Stop bit is set to 1 on Voice Prompt Generation command, or Idle command is issued.
VOICE ACTIVITY
6.Get the timer status. (Request Code = 0101) The response word is 1 if the MX93030A internal timer has been set before with Set Time/OPT0-7/Voice Prompt/Silence Threshold command. Otherwise, the response word is 0. 7.Get the message attribute. (Request Code = 0110) To show the specified message is of MEMO type (response word =1) or ICM type (response word = 0) 8.Get the Del Mark status. (Request Code = 0111) To show the specified message has been tagged a Del Mark (response word = 1) or not (response word = 0) 9.Get the template Old Mark status.(Request Code=1000) To show the specified message which has been tagged a temp. Old Mark (response word=1) or not (response word=0) 10.Get the link index, that stored in message. 11.Write link index to specified message. 12.Check OGM existence. (Request Code = 1111) Use this command to show whether an OGM with the Msg ID is recorded (response word = 1) or not (response word = 0). All the results are reported in the response word. In this mode the HOST can set the VOX threshold in bit 0-11. The Hexadecimal numbers for VOX level are listed in Table 6.
SET LOOP-BACK/PERSONAL MAIL
Three functtions are provided in this command shown as follows: 1.Set the personal mailbox number In this mode the HOST can select one out of eight mailboxes (setting in bit 0-2) for recording messages, playing recorded message and retrieving message time. Each mail box manages its own messages and Msg IDs. The default mailbox is number 0. 2.Set the recording message attribute Before recording a message, the HOST can set the attribute of that message to be MEMO or ICM. Clear bit 3 to zero to identify a recorded message as an ICM or set bit 3 to one to identify a recorded message as a MEMO. Make sure to set the desired mailbox before issuing the message related commands such as Record, Play, Delete Message and Get message Time. 3.Set the loop back function Before recording a message, the Host should set the recording signal loop back function to be enabled or

disabled. Clear LB (bit4) to zero for transmitting back the signal that is received through the codec input. Set LB (bit4) to one for disabling the received signal to be transmitted back to codec. selected to be cooked data, the HOST should further specify the parameter to be read out by setting the desired request code. In cooked data mode, there are fifteen request codes for the HOST to get different caller ID parameters. 1.Message type (request code=0000). 2.Message length (request code=0001). 3.Parameter length of Date & Time (request code=0010) 4.Date & Time (request code=0011). 5.Parameter_length of Directory Number (request code=0100). 6.Directory Number (DN) (request code=0101). 7.Parameter length of Reason for absence of DN (request code=0110). 8.Reason for absence of DN (request code=0111). 9.Parameter length of Caller Name(request code=1000). 10.Caller Name (request code=1001). 11.Parameter length of Reason for absence of name (request code=1010). 12.Reason of absence of Caller Name(request code=1011). 13.Checksum (request code=1100). 14.Parameter length/visual indicator. 15.Visual indicator. The MX93030A responds the requested data on low byte of response word and reflects the related flags on high byte of response word. The CD flag (bit 15) indicates a valid carrier is present on the line. The ERR flag (bit 14) shows the decoded data is not correct due to wrong checksum detected or buffer overflowed. The DR flag (bit 13) is set when a valid FSK data of current frame is output. The EOF flag (bit 12) shows one complete frame of FSK cooked data is read out. The raw data is generated on real time basis. Although the demodulator output is buffered by the MX93030A, the HOST should read out the raw data byte at least every 6 ms to prevent buffer overflow. If the HOST selects raw data mode, the request code on command word (bit 4-7) is neglected. All the cooked data parameters are buffered in the internal memory of MX93030A until other commands are issued by the HOST. When the next bit streams are coming, the proviously buffered parameters will be lost. The MX93030A will return to Idle mode when an Idle command is issued.
TELEPHONE NUMBER
In this mode the HOST can write/read telephone number to/from the MX93030A with the sequence of telephone number command as follows: 1.Write telephone number to the MX93030A. The first command defines the telephone record ID(bit 05) and set W/R (bit 10) to zero. Following command specifies the one-byte to be stored under that ID. While the current record ID is full, the MX93030A will show the status in response word (bit0, FULL) The MX93030A will terminate telephone number mode and return to Idle mode when stop (bit 9) is set to 1 on telephone number command or Ilde command. 2.Read telephone number from the MX93030A. The first command defines the telephone record ID(bit 05) and set W/R (bit 10) to one. The telephone data will be shown on the response word. Following command shows the one-byte data on the response on the HOST. The reponse word contains the byte-data (bit 0-7) and Read End(bit 8). When the Read End bit is 1, the bytedata is invalid. The MX93030A will terminate telephone number mode and return to Idle mode when stop (bit 9) is set to 1 on Telephone Number command or Idle command.
CALLER ID The MX93030A is capable of FSK demodulation and frame data interpretation according to the requirements of Bellcore CLASS feature. When start\_bit (bit 0) of Caller ID command is set to 0 from the HOST, the MX93030A starts to perform FSK demodulation. The Host could specify the data output mode by setting bit 8 to be raw data (=0) or cooked data (=1). If output mode is

POWER-DOWN ARAM mode:
When power failure happens, the PWD\ should go low at least 5 ms and RST\ should be high at least 100 ms for the MX93030A to terminate any operating mode and enter power-down mode. To keep the ARAM and internal RAM data correct during power failure, a battery backed 5V DC supply is needed to be connected to the MX93030A and ARAM. While in power-down mode, the MX93030A will not respond to any command from the HOST, refreshing ARAM is continued and system runs with low crystal 32768 Hz to save backup power.
