6.0 FUNCTIONAL DESCRIPTIONS
HOST INTERFACE The host interface port is a 16-bit bidirectional register. The host can access this register via 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 fetches the content of the register. PACKB\ is defaultly set to high. When DSP writes a response to this register, PACKB\ is set to low. When host has read this register, PACKB\ will be reset to high. Note that the host accesses this register by low byte first, and then high byte. ARAM MANAGEMENT ARAM types and specifications supported by the MX93021 are as follows: 1. ARAM type : - 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 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, and total bad clusters are less than 25% of total clusters. - 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.

Voice Message Recording and Storage
The MX93021 provides a high quality 4.8 kbps speech compression technique to permit over 14 minutes of speech storage in each 4M bit of DRAM device. The chip supports up to 63 variable length incoming and outgoing messages that are labeled as Msg ID 1 to 63. Although ICM could range from Msg 1 to 63, Msg IDs 63 to 57 are the only places for outgoing messages (OGM) storage so that the deletion and 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 MX93021 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 ms from the memory using a Record Pause command with assigned Tail Cut Factor. The MX93021 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 MX93021.
Message Playback
Random access for playback of any new message or message with specified Msg ID is supported by the MX93021. During playback, the MX93021 also monitors the telephone line signals, and Play Pause function is provided. The MX93021 is able to fast-forward the playback of a recorded message, and the playing speed will be up to 33%.
Message Deletion
The MX93021 provides two ways to delete recorded ICMs. One is the two-step method -- the combination of Del Mark and Real Del on Play command, and the other is the immediate method -- Delete command. The twostep 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 MX93021 utilizes the built-in speech decoder and an external EPROM/ROM (minimum access time is 120ns) to store the vocabulary. The chip supports up to a 62-Kword EPROM/ROM that allows 3.44 minutes of voice prompts storage. The vocabulary supports up to 255 phrases. Given a phrase number in the Voice Prompt command from the HOST, the MX93021 outputs the corresponding utterances to the Codec interface. The starting address of voice prompt data could be located at address 800hex, 4800hex, or 8000hex. During playback of the voice prompt, the MX93021 monitors the telephone line signals.
Announcement (ANNC) Record
The MX93021 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.
New/Old Message
For the HOST to manipulate incoming messages more handily, the MX93021 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 PLAY command. After Real Del is issued, all new/old ICM Msg IDs will be rearranged. The functions, Play-new or Delete-all-old messages, are provided by the MX93021 in the command set.
Time Keeping
There is a timer clock in the MX93021. 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.

DTMF Detection
For remote control operation of the answering machine, the MX93021 monitors the incoming telephone line signal to detect the presence of DTMF signal.
Personal Mail
The MX93021 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 MX93021. The levels and frequencies are programmable by the HOST.
Speed Dial Telephone Number Storage
The MX93021 may store up to 2048 words for telephone number storage. The 2048 words of memory in ARAM area could be also used for other special purpose, and are backed up during power down mode.
Call Progress Tone Detection
The MX93021 supports the detection of call progress tones within the band of 330-660 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.
Power Down
With the power of backup batteries, the MX93021 is capable of keeping messages and data stored in the ARAM during power failure. In power down mode, the MX93021 will run at a lower clock rate to reduce power consumption and keep refreshing the ARAM.
Near End Echo Cancellation
The MX93021 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 VII.
Query and Report
The MX93021 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 of ARAM, the time of recorded message, and the ARAM good/bad check.

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. The checksum of ARAM and internal SRAM will be calculated and stored before entering power-down mode . After power up, the MX93021 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 MX93021 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 MX93021 will initialize all the system parameters to their default values. After completing the above system initialization, the MX93021 will send its status of warm/cold start to the HOST, set ACK\ to low and enter Idle mode. The HOST should poll the ACK\ to read the status word, 0000h for cold start and 0100h for warm start. After being reset, the MX93021FC will first do self test and initialization, then it will set pin-14 (PACKB\) low to indicate host processor. But before the signal (PACKB\ setting to low) appears, there will be a pulse about 6us shown up in pin-14. Host processor should ignore that pulse. Please see detailed in the following timing diagram.
MODES OF OPERATION
After reset, the MX93021 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 and Voice Prompt, require Stop command to return to Idle mode. The MX93021 supports 14 modes of operation, that are listed as follows: Command 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Mode Name Record Play Message status Tone Generation Line Monitor Delete Message Set Current Time & OPT Get Current Time & OPT & IPT Initial & Test Memory Get Record Message Time Voice Prompt Voice Activity Personal Mail Telephone Number

DESCRIPTION OF MODES OF OPERATION
Record
When Record command is received from the HOST, the MX93021 performs speech compression, stores the message into ARAM, 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 MX93021 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. 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 from the memory by using a Record command with assigned Tail Cut Factor (bit 05). While system memory is full, the MX93021 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 MX93021 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 Record, Get Time & OPT & IPT, Set Time & OPT and Tone Generation. The MX93021 will terminate Record mode and return to Idle mode when Stop bit on Record command is set to 1. Note: The MX93021 supports up to 63 incoming and outgoing messages recording which are labeled as Msg ID 1-63. The Msg IDs of incoming message are labeled chronologically and rearranged automatically after recording. Although ICM could range from Msg 1 to 63, Msg IDs 63 to 57 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=63 - maximum OGM number that will be applied in user's specification.)
Play
When Play command is received from the HOST, the MX93021 performs message playback and line monitoring. The Msg ID (bit 0-5) 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 MX93021 will search to play the non_played message with specified Msg ID. During playing, the HOST can pause playback by setting Pause (bits) 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 6) on play command. After being tagged a Del Mark, the marked message is not really deleted until a Real Del (bit 7) is set. 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 MX93021 stops playback but still remains in Play mode. The MX93021 will response to the Play_End flag if the HOST wants to play invalid or nonexistent messages. In playing, all commands will be ignored except Play, Get Time&OPT&IPT, and Tone Generation. The MX93021 will terminate Play mode and return to Idle mode when Stop bit, Del Mark bit or Real Del bit is set to 1 on Play command.

MX93021
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.
Line Monitor
In this mode the MX93021 monitors the telephone line signal for the detection of DTMF, Call Progress Tone, Vox, and/or Continuous Tone. The MX93021 keeps monitoring the line until Stop bit is set to 1. The MX93021 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 #
Tone Generation
In this mode, up to double tones can be generated by the MX93021. 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)) 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 MX93021 starts tone generation only after receiving the third command. The MX93021 will terminate Tone Generation when Stop bit is set to 1 on Tone Generation command.
The MX93021 will terminate Line Monitor mode and return to Idle mode when Stop bit it set to 1 on Line Monitor 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 05 and clear bit 11, 10 and 7 to zero. 2.To delete all old ICM, set Del_All_Old (bit 7) to 1 and clear bit11, 10 to zero. (Bit 0-5 is ignored) 3.To delete a specified new ICM, set Del_New_Msg (bit 10) to 1, give the New Msg ID in bit 0-5, clear bit 11, 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 0-5 and clear bit 10, 7 to zero.

MX93021
If the HOST deletes invalid or nonexistent messages, an error flag will show on bit 0 of the response word.
Initial & Test Memory
In this mode there are 6 functions for the HOST to define:
Set Current Time & Output Port
In this mode the HOST can set the current time to the internal timer clock of the MX93021. The time information includes second, minute, hour and week. The timer in the MX93021 will be used to stamp time and data 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 OPT 8-13, put the output data in bit 0-7 and use request code(bit 8-11) 0101.
1.ARAM Initialization
The HOST can initialize the ARAM by setting Init ARAM (bit 0) to 1. This function is normally used after first powerup of the system. The HOST must send this command to the MX93021 in order to format ARAM. The MX93021 performs ARAM formatting to determine the ARAM size (address space and bit width) and detect the good/bad memory unit of ARAM. The response word reported to the HOST contains the information of ARAM bit size (bit 0-3), ARAM address size (bit 4-7) and ARAM good/bad status (bit 8). If the examination in the initialization shows that the ARAM quality meets the pre-defined specification, the MX93021 responses 1 in ARAM good/bad status bit. After initialization, all messages in the ARAM are lost.
2.ARAM Pattern Check
The MX93021 allows the HOST to check the status of ARAM by setting the ARAM Check (bit 1) on this command. By checking the patterns, produced in Initialization ARAM mode and stored in ARAM, the MX93021 can identify the current ARAM status to be good or bad.
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.
Get Current Time, Output Port & Input Port
In htis mode the HOST can get the current time from the internal timer clock of the MX93021. 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. 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
4.To get week, use request code (bit 8-11) 0011. 5.To get OPT 0-13, use request code (bit 8-11) 0100. 6.To get OPT 0-13, use request code (bit 8-11) 0101. 7.To get IPT 0-5, use request code (bit 8-11) 0110. The requested data will be reported in the response word. 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.

MX93021
6. Word/Byte
The Word/Byte (bit 8) defines the way that the MX93021 accesses voice prompt data. By setting this bit to 1, the voice prompt data is accessed by the MX93021 with the unit of word, else with the unit of byte.
Voice Prompt
In this mode the MX93021 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 MX93021 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 generation mode, the MX93021 keeps monitoring the line signal and sends the results in response word to the HOST. The MX93021 will terminate Voice Prompt Generation mode and return to Idle mode when Stop bit is set to 1 on Voice Prompt Generation command.
Get Record Message In this mode, there are nine 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 MX93021 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) 6.Get the timer status. (Request Code = 0101) The response word is 1 if the MX93021 interal timer has been set before with Set Current Time 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.Check OGM existence. (Request Code = xxxx) This submode command works only when the memory specified by the Msg ID is exclusively for OGM storage. 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.
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 VII.
Personal Mail
Two functtions are provided in this command 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 for recording a message as an ICM or set bit 3 to one for recording a 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.

MX93021
Telephone Number
In this mode the HOST can write/read telephone number to/from the MX93021 with the sequence of Telephone Number commands as follows: 1.Write telephone number to the MX93021. The first command defines the telephone directory index (bit 0-10) and W/R (bit 11). The second command specifies the one-word data to be stored under that index. 2.Read telephone number from the MX93021. The command defines the telephone directory (bit 0-10) and W/R (bit 11). The telephone data will be shown on the response word.
HOST INTERFACE PERFORMANCE
Power-Down
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 MX93021 and ARAM.
The signal of power failure indication is connected to the MX93021 through PWD\ pin (pin 15). A reset signal (RST\) is also connected to the MX93021 (pin 96). When power failure happens, the PWD\ should go low at least 5 ms and RST\ should be high at least 60 ms for the MX93021 to terminate any operating mode and enter power-down mode. While in power-down mode, the MX93021 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.
