6.0 FUNCTIONAL DESCRIPTIONS
HOST INTERFACE The command and response of the MX93022A is represented by an 16-bit code. The MX93022A supports the synchronous serial and 8-bit parallel communication protocal 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.

AFLASH MANAGEMENT The MX93022A supports SAMSUNG KM29N040, KM29N160 and TOSHIBA TC58A040 Flash memory management. 1.128K x 8 (KM29N040 x1, TC58A040x1) 2.256K x 8 (KM29N040 x 2, TC58A040x2) 3.512K x 8 (KM29N160 x1)
New/Old Message
For the HOST to manipulate incoming messages more handily, the MX93022A 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 MX93022A in the command set.
Voice Message Recording and Storage Message Playback
The MX93022A 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 MX93022A also monitors the telephone line signal to detect the presence of DTMF, Call progress Tone and Continuous Tone and responses to 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 MX93022A 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 MX93022A. This Loop-Back function can be disabled by the host in the personal mail command. Random access for playback of any new message or message with specified Msg ID is supported by the MX93022A. During playback, the MX93022A also monitors the telephone line signals, and Play Pause function is provided. The MX93022A is able to fast-forward the playback of a recorded message, and the playing speed will be up to 33%.
Message Deletion
The MX93022A 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.
Voice Prompt
For high-quality Voice Prompt playback, the MX93022A 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 MX93022A 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 MX93022A monitors the telephone line signals.

Announcement (ANNC) Record
The MX93022A 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.
INDEX
MX93022A
Time Keeping
There is a timer clock in the MX93022A. 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.
Query and Report
The MX93022A 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.
DTMF Detection Personal Mail
For remote control operation of the answering machine, the MX93022A monitors the incoming telephone line signal to detect the presence of DTMF signal. The MX93022A 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.
Tone Generation
Up to double tones can be generated by the MX93022A. The levels and frequencies are programmable by the HOST.
Speed Dial Telephone Number Storage
The MX93022A can store up to 63 sets for telephone number storage. Each set supports 13bytes. These memory could be also used for other special purpose.
Call Progress Tone Detection
The MX93022A 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
The MX93022A 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.

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 MX93022A will initialize all the system parameters to their default values.
MODES OF OPERATION
After reset, the MX93022A 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 MX93022A supports 15 modes of operation, those are listed as follows: Command 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 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

After completing the above system initialization, the MX93022A 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 MX93022A and check the response status. If needed, the HOST should set the parameter by sending the relative command.

DESCRIPTION OF MODES OF OPERATION
RECORD
When Record command is received from the HOST, the MX93022A 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 MX93022A 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 MX93022A 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 MX93022A 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 MX93022A 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. Note: The MX93022A 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 MX93022A is off, the current recording message will be discarded.
PLAY
When Play command is received from the HOST, the MX93022A 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 MX93022A 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 MX93022A stops playback but still remains in Play mode. The MX93022A will respond to the Play_End flag if the HOST wants to play invalid or nonexistent messages.

INDEX
MX93022A
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 MX93022A 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. 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 MX93022A 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 MX93022A starts tone generation after receiveing the first command which defines the gain in bit 0-3. The MX93022A will terminate tone generation when Start/Stop bit is set to 0 on Tone Generation command.
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.
TONE GENERATOR
In this mode, up to double tones can be generated by the MX93022A. 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
LINE MONITOR
In this mode the MX93022A monitors the telephone line signal for the detection of DTMF, Call Progress Tone, Vox, and/or Continuous Tone. The MX93022A keeps monitoring the line until Stop bit is set to 1. The MX93022A 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 #
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))

MX93022A
DELETE MESSAGE
This mode provides an immediate way to delete messages as follows: 8.To set MX93000, put the control data in bit 0-7, specify register in bit 8-10 and set bit 11 to 1.
GET TIME/OPT/IPT
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 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. 3.To delete all old ICM, set Del_All_Old (bit 7) to 1 and clear bit11, 8 to zero. (Bit 0-6 is ignored) 4.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. In this mode the HOST can get the current time from the internal timer clock of the MX93022A. 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. 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.
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 MX93022A 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 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. 7.To set silence threshold, use request code (bit 8-11) 0111.
13
7.To get IPT 0-7, use request code (bit 8-11) 0110. The requested data will be reported in the response word.
INITIAL & TEST MEMORY
In this mode there are 6 functions for the HOST to define:
1.Momory Initialization
The HOST can initialize the 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 MX93022A in order to format MEMORY. The MX93022A performs MEMORY formatting to determine the MEMORY size 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 pre-defined specification, the MX93022A responds 1 in G/B status bit. After initialization, all messages in the MEMORY are lost.
2.Memory check & error correct
The MX93022A allows the HOST to check the status of MEMORY by setting the mem. Check (bit 1) on this
INDEX
MX93022A
command. In the same time, it also completes the memory error correct. 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) 6.Get the timer status. (Request Code = 0101) The response word is 1 if the MX93022A 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.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.
3.Line On/Off
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
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.
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.
VOICE PROMPT
In this mode the MX93022A plays 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 MX93022A 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 MX93022A keeps monitoring the line signal and sends the results in response word to the HOST. The MX93022A 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.
14
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 MX93022A 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)
INDEX
MX93022A
VOICE ACTIVITY
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. The MX93022A 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 MX93022A. 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 MX93022A 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.
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.
POWER-DOWN
The message and all memory management information store in AFLASH memory, thus there is no need to maintain the power to preserve stored memory. If the microcontroller real time clock is used to maintain the time and day, neither the AFLASH nor the MX93022A require battery backup during power failure. In this case, when returning to normal operating mode, the microcontroller should set the time and day. While in Record mode or Telephone Number mode, if power failure happens, the power supply of the MX93022A is off, the current recording message or storing telephone ID will be considerd as failure. When power failure happens, the PWD\ go low at least 10ms before the supply power of, the current recording message or storing telephone ID will be valid. POWER DOWN TIMING (AFLASH)
10ms PWD\
TELEPHONE NUMBER
In this mode the HOST can write/read telephone number to/from the MX93022A with the sequence of telephone number command as follows: 1.Write telephone number to the MX93022A. 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 MX93022A will show the status in response word (bit0, FULL)
VDD
Note: While in power down mode, the OPT7-0 will be reset to low.
