6.0 FUNCTIONAL DESCRIPTIONS
HOST INTERFACE (MCU MODE)
The command and response of the MX93032-M1 are made up by a 16-bit code. The protocol that one command sent
and one response received must strictly be obeyed by HOST ; otherwise, dead lock will occur. Meanwhile, both
parallel interface and serial interface are provided by the MX93032-M1.
8-bit parallel :
A 16-bit code can be accessed by HOST two times via setting PHILO pin. For writing operation, the HOST write the
low byte of the command into the register of DSP, when PHILO is pulled to low, DSP does nothing but latches data.
Following, PHILO is set to high and high byte of command is written into register, then DSP will perform the command
issued by HOST and send out the response. DSP will pull PACK\ to be low to indicate that response is ready. HOST
must read the low byte and then high byte sequentially. PACK\ will reset to high when the high byte is read by HOST.
All of the description given above will be illustrated by the following timing chart.

Decision Rules between MCU mode and DSP Mode:
1. The contents located on 0xE000 and 0xE001 are 0x1234 and 0x5678, It will be considered as external DSP mode.
This configuration is used for developing customer’s control codes on MXIC’s MX93032-M1 IC with standard
code.
2. The contents located on 0x680E and 0x680F are 0x5678 and 0xA988, it will be considered as MCU mode. This is
the only one configuration for MCU mode under developing and mass production.
3. Either the content located on 0x680E and not 0x5678 or that located on 0x680F are not 0xA988, it will be considered as DSP mode. The configuration is used for mass production for DSP mode adopted.
4. The decision priority depends on the items order. That is, the item labeled with smaller number has higher priority.
CONTROL CODE CONFIGURATION (DSP MODE)
There are two configurations for customer development or production.
Configuration 1 :
In this configuration, the BIOS+ALGORITHM and control codes are all running in the external high-speed EPROMs
or SRAMs. The MX93032-M1 pin 97 (EROM) must be set to high.

MX93032
MX93032-M1
coming 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 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.
Each message can be recorded by either 4.8K or 12.8K
compression rate depending on system programmer’s
assignment.
The MX93032-M1 provides DSP embedded functional
modules, including speech compression/decompression,
telephone line signal processing, ROM voice prompt,
Macronix MX29F16A Flash management, time keeping
and full duplex speaker phone.
In MCU mode, the MX93032-M1 service is requested
via a command call with 16 bits parameter sent by Micro
controller, and answered 16 bits sent by DSP. In DSP
mode, user's system control program can be masked-in
the MX93032.
During recording, the MX93032-M1 also monitors the
telephone line signal to detect the presence of DTMF,
Call Progress Tone and Continuous Tone and responses
to the control program. The HOST can stop recording,
and delete the last n*400ms/200ms from the memory
using a Record command with assigned Tail Cut factor.
The MX93032-M1 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 MX93032-M1 supports 16 modes of service and
responses useful to operational information about timing, FLASH utilization, detected DTMF, etc.
Hereafter, HOST means "external micro-controller" for
MCU mode, and it means "system control program"
for DSP mode.
FLASH MANAGEMENT
The recording voice signal, received through the CODEC
input, is transmitted back to the CODEC output by the
MX93032-M1 service commands.
The MX93032-M1 uses MXIC's MX29F16A FLASH as
storage device for message and/or voice prompt data.
Up to two MX29F16A can be supported by the MX93032M1 service command.
OUTGOING MESSAGE (OGM) RECORD
The MX29F16A is a 16M-bit FLASH memory organized
as 1M word x 16. It includes 16 sectors (each sector is
64K words) and some of these sixteen sectors are bad.
To manage the MX29F16A, the MX93032-M1 will detect
and then give up bad sectors and only utilize the good
sectors. For the purpose of storage efficiency, each good
sector is further divided into 32 blocks (each block contains 2K words). Each block can store speech data of
about 6.8 seconds for 4.8kbps compression algorithm
and 2.55 seconds for 12.8kbps compression algorithm.
The MX93032-M1 provides flexible recording ways for
outgoing message. The HOST can select to delete the
old OGM before a new one is recorded or to abort the
new OGM record without losing the old OGM.
NEW/OLD MESSAGE
For the control program to manipulate incoming messages more handily, the MX93032-M1 keeps an internal
record of the ICM to identify the new/old status of messages.
MESSAGE RECORDING AND STORAGE
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, Play
New or Delete All Old messages , are provided by the
MX93032-M1 in the command set.
The MX93032-M1 provides high quality speech compression techniques for recording and playback functions. It
can permit over 15 minutes or 40 minutes of speech
storage in each 16M bit of MXIC's MX29F16A FLASH
device based on 12.8K or 4.8K compression rate, respectively.
The MX93032-M1 supports up to 127 variable length in-

MX93032
MESSAGE PLAYBACK
sages, the HOST should set the corresponding mailbox
number first with Personal Mail command.
Random access for playback of any new message or
message with specified Msg ID is supported by the
MX93032-M1. During playback, the MX93032-M1 also
monitors the telephone line signals, and Play Pause function is provided. The MX93032-M1 is able to fast-forward
the playback of a recorded message, and the playing
speed will be up to 33 %.
TIME KEEPING
There is a timer clock in the MX93032-M1. 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 message.
MESSAGE DELETION
DTMF DETECTION
The MX93032-M1 provides two ways to delete recorded
ICMs. One is the two-step method - the combination of
Del Mark and Real Del on Play and Delete command,
and the other is the immediate method - Delete command. The two-step method enables the control program
to handle the deletion more flexibly, while the immediate
method deletes a specified message directly.
For remote control operation of the answering machine,
the MX93032-M1 monitors the incoming telephone line
signal to detect the presence of DTMF signal.
TONE GENERATION
Up to double tones can be generated by the MX93032M1. The levels and frequencies are programmable by
the HOST.
VOICE PROMPT
For high-quality voice prompt playback, the MX93032M1 utilizes the built-in speech decoder and external
EPROM/ROM or FLASH to store the vocabulary. The
MX93032-M1 also supports up to a 32K-word external
EPROM/ROM that allows minimum 1.8 minutes of voice
prompt storage. If voice prompt data is stored in FLASH,
space of maximum 60K words (minimum 3.4 minutes) is
permitted. The external (upper part) voice prompt is also
allowed. But if FLASH voice prompt is enabled, the external voice prompt will be disabled. The vocabulary supports up to 255 phrases. Given a phrase number in the
Voice Prompt command from the HOST, the MX93032M1 outputs the corresponding utterances to the Codec
interface. The starting address of external voice prompt
data could be located at data address 1000H, or program address 8000H.
CALL PROGRESS TONE DETECTION
The MX93032-M1 supports the detection of call progress
tone 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 tone is responded to the control program, and
could be used to terminate recording.
NEAR END ECHO CANCELLATION
The MX93032-M1 implements a near end echo canceller in software to enhance the detection of DTMF and
Call Progress Tone during Playback and Voice Prompt
mode.
During playback of the voice prompt, the MX93032-M1
monitors the telephone line signals.
FSK Decoder
PERSONAL MAIL
All of the services, Calling Number Delivery (CND), Calling Name Delivery (CNAM) and Calling Identity Delivery
on Call Waiting (CIDCW), exploit the Frequency Shift
Keying (FSK) method to transmit the desired data from
the SPCS to CPE. Depending on the specific service,
The MX93032-M1 supports up to 8 mailboxes that may
be used for personal mail application. Each mailbox has
its own ICM/MEMO Msg ID. The total Msg.ID is 127 for
all of mailbox. Before recording, playing or deleting mes-

data transmission may occur with the CPE in an onhook state or in an off-hook state. The specifications for
data transmission are given on SR-TSV-002474 which
are classified into three layers, physical layer, data linker
layer and message assemble layer. The MX93032-M1
only takes the responsibility to decode physical layer.
For Data link layer (Check Sum) and Message Assemble
layer (the meaningful data), system should take care.
The performance test associated with physical layer
based on SR-3004 will be given on Appendix A.
Note:
on the both ends, but also prevent feedback instability
(singing) from occurring. Moreover, the MX93032-M1 provides automatic gain control (AGC) for microphone channel which helps the outgoing voice to keep at a desired
level especially for a moving talker, and speaker volume
control which allows the user to adjust the speaker volume for his need. In addition, DTMF/Tone generations
and call-progress tone detection are also provided.

CAS Detection
For Calling Identity Delivery on Call Waiting, the MX93032M1 will monitor the presence of CPE alerting signal according to the specification given on Bellcore Special
Report SR-TSV-002476.
VOX DETECTION (DIGITAL VOICE ACTIVATED RECORDING)
The speech detection is implemented on the MX93032M1 to indicate whether the recording signal level is above
the VOX threshold. If the control program 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.
SPEAKERPHONE
The speaker system provided by the MX93032-M1 contains two adaptive filters which are called as acoustical
echo canceller (AEC) and line echo canceller (LEC). The
purpose of AEC is used to cancel the acoustical echo
between microphone and speaker which is caused by
the sound reflection within space. A LEC cancels the
echo resulted by the 4 to 2 wire telephone line connection and impedance mismatches between customer premises and the central office.
When speakerphone is activated, the algorithms associated with AEC and LEC not only reduce the echo heard

DAA CONSIDERATION FOR SPEAKER PHONE
It should be emphasized that DAA circuit plays an important role on improving the performance of speakerphone. This
sub section gives some guides on how the DAA circuit may be "tuned". A diagram of DAA circuit must be given for
simplifying the flowing interpretation.

Referring to figure given above, we have 4 analog amplifiers which are
1.Microphone Pre-Gain (MIC GAIN)
2.Line Out Gain (LINE DRV)
3.Line in Pre-Gain (LINE GAIN)
4.Speaker amplifier (SPK DRV)
Obviously, the 4 amplifiers together with the Line Out volume, Speaker Volume, receive attenuator, transmit attenuator, two volume compensators, acoustical coupling function Hac(f) and line coupling function Hlin(f) compose a
closed loop system. The AEC and LEC will provide additional attenuation to the loop gain one they converge.
To have a better performance on speaker phone, we strongly recommend that analog gain of DAA must satisfy the
following two criteria:
1.As the near end (Microphone side) speaks only, the level at Codec 2 should fulfill that, "codec 2 input must
be less than Codec 2 output due to electrical echo". This meaning can be expressed as
LINE_DRV * Hlin(f) * LINE_GAIN < 1
2.As the far end (Line Side) speaks only, the level at Codec 1 should fulfill that, "Codec 1 output must be
greater than Codec 1 input resulting from acoustical echo". This meaning can be expressed as
SPK_DRV * Hac(f) * MIC_GAIN < 1
By considering the criterion 1, it should pay more attention that minimum echo should be reached by improving the
telephone line interface ( that is, reducing Hlin(f)) and not by reducing LINE_GAIN due to that the MX93032-M1 must
obtain the high enough signal to process. For the same reason for criterion 2, the low echo should be achieved by
good acoustical and mechanical decoupling rather than by decreasing MIC_GAIN.
The ultimate target for hardware design is to create one system which not only satisfies two criteria given above, but
also provides a desirable volume to both speaker and telephone.

QUERY AND REPORT
The MX93032-M1 is capable of reporting to the control program 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 FLASH, the time of recorded message, and the FLASH good/bad check.
POWER DOWN
With the power of backup batteries, the MX93032-M1 is capable of keeping messages and data stored in the FLASH
during power failure. In power down mode, the MX93032-M1 will run at a lower clock rate to reduce power consumption.
CRYSTAL CONNECTION
The MX93032-M1 allows two ways of crystal connections :
1. Normal approach: use both high crystal (32.256 MHz) and low crystal (32768 Hz). To enable this mode, the FLLEN\
(54) pin must be connected to VDD. In this mode, the DSP high clock is generated from the high crystal directly,
and the low crystal is mainly used in power down mode.
2. FLL (Frequency-Locked-Loop) approach: use only low crystal (32768 Hz). To enable this mode, the FLLEN\ (54) pin
and X2 (89) pin must be connected to ground and the X1 (88) pin to VDD. In this mode, the low crystal is to generate
all the DSP system clocks and the high crystal can be saved to reduce the overall system cost.

When the system is powered up, the RST\ pulse will make the MX93032-M1 to run programs from address 0. After
check sum of internal ROM codes checked and some essential initialization of DSP are finished. In MCU mode, the
MX93032-M1 is ready to poll the command issued by the HOST and indicate the HOST by setting PACK\ or SI\ to be
low. The HOST should poll the indication sent by the MX93032-M1 and read out the pseudo response first. Following
some necessary initialization given below must be set by HOST .
1. Set telephone data configuration
2. FLASH initialization depending on the FLASH good/bad check
3. Codec initialization if necessary

IDLE :
This command is allowable to be issued within any other operation which is processing. As soon as the MX93032-M1
receives Idle command, the original operation will be stopped automatically.
RECORD
When Record command is received from the HOST, the MX93032-M1 performs speech compression, stores the
message into FLASH, and monitors telephone line. If the VOX Record bit had been set to 1 on Initial and Test Memory
command, recording of the speech will start upon the voice activity detected, else the MX93032-M1 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 and Test Memory command, the HOST can choose to delete the old OGM
before a new one is recorded. If that bit is cleared to 0, the new OGM recording can be aborted without losing the old
OGM 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*400ms/200ms from the memory by
using a Record command with assigned Tail Cut factor (bit 0-5).
While system memory is full, MX93032-M1 will stop message recording, show the status in response word (bit 7,
Mfull).
During Record mode, the HOST can instruct the MX93032-M1 to generate a tone by issuing the DTMF Generator
command. Setting Stop bit on DTMF Generator command will stop tone generating.
The MX93032-M1 will terminate Record mode when Stop bit on Record command is set to 1.
Note: The MX93032-M1 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 ID 1 to 127, Msg IDs 127 to 121 are the only places 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.)
PLAY
When Play command is received from the HOST, the MX93032-M1 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 (non-played
one), set Play New (bit 10) to 1, then the MX93032-M1 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%.
P/N:PM0689
REV. 1.0.3, DEC. 13, 1999

MX93032
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 (Delete Message mode bit 8) 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 issue 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 MX93032-M1 stops
playback.
The MX93032-M1 will terminate Play mode when Stop bit or Del Mark bit is set to 1 on Play command.
MESSAGE STATUS
In this mode, there are 6 request codes for the HOST to get message information;
1.
2.
3.
4.
5.
Get the number of personal recorded messages (request code = 0)
Get the number of personal new messages (request code = 1)
Get the number of personal old messages (request code = 2)
Get the available recording time with unit of second (request code = 3)
Get the number of total recorded messages (request code = 8)
The result will be reported in the response word.
DTMF GENERATOR
In this mode, up to double tones can be generated by the MX93032-M1. The tone levels and frequencies are programmable and controlled by the HOST. The DTMF Generator 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 3 dB (gain code 0000) to -25 dB (gain code 1110) with
2 dB resolution. For DSP mode, the frequencies are defined in the variables BUF1 and BUF2. For MCU mode, three
steps of commands should be issued, first, DTMF sent and signal Gain should be set, following the corresponding
two frequencies should be specified. The frequency code and its frequency represented is according to 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 MX93032-M1 starts tone
generation only after receiving the start command.
The MX93032-M1 will terminate DTMF Generator when Stop bit is set to 1 on DTMF Generator command.

In this mode the MX93032-M1 monitors the telephone line signal for the detection of DTMF, Call Progress Tone, VOX,
and/or Continuous Tone. The MX93032-M1 keeps monitoring the line until Stop bit is set to 1.
The MX93032-M1 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 :

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 0-6 and clear bit 11, 10 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, 7 to zero.
3. To delete all old ICM, set Del All Old (bit 7) to 1 and clear bit 11, 10 to zero. (Bit 0-6 is ignored)
4. To erase the "Del Mark" from a specified ICM ("Del Mark" is a tag set on Play command for deletion), set Del Mark
Clr (bit 11) to 1, give the Msg ID in bit 0-6 and clear bit 7 to zero.
SET CURRENT TIME/VOICE PROMPT/SILENCE THRESHOLD
In this mode the HOST can set the current time to the timer clock of the MX93032-M1. The time information includes
second, minute, hour and week. The timer in the MX93032-M1 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.

GET CURRENT TIME
In this mode the HOST can get the current time from the timer clock of the MX93032-M1. 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.
The requested data will be reported in the response word.
INITIAL AND TEST MEMORY
In this mode there are 9 functions for the control program to define;
1. FLASH Re-Initialization
The HOST can re-initialize the FLASH by setting FLASH Re-Init (bit 0) to 1. After receiving this command, the
MX93032-M1 will erase all the messages and data stored in the FLASH and then re-format the FLASH to establish
the management structure. The response word reported to the control program contains the information of FLASH bit
size (bit 0-3) , FLASH address size (bit 4-7), FLASH good/bad status (bit 8) and FLASH good rate (bit 9-15). After reinitialization, all messages and data in the FLASH are lost.
2. FLASH Initialization or Error Correction
The HOST can perform FLASH first-time initialization or error correction by setting FLASH Init (bit 1) to 1. First-time
initialization is to format a new FLASH and then establish the management structure, while error correction is to
correct the problems that may result from power loss during operation. This function is normally used after first powerup of the system. The response word reported to the control program contains the information of FLASH bit size (bit
0-3) , FLASH address size (bit 4-7), FLASH good/bad status (bit 8) and FLASH good rate (bit 9-15).
3. FLASH Garbage Collection
Due to the characteristics of MX29F16A FLASH and the management structure, when messages are deleted, the
data regions occupied by them will not be released to be available immediately. To free out such regions, the MX93032M1 provides a two-step mechanism. First is to check the FLASH garbage collection recommendation status by
Message Status command and, if garbage collection is recommended, then to issue bit 2 (Garbage Collect) on this
command to perform the corresponding garbage collection actions.
4. Line On/Off
The HOST should set Line On/Off (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.
5. VOX On/Off Record
If the HOST turns on the VOX Record function (by setting bit 4 to 1) on this command, speech recording will start upon
the voice activity detected, else recording will start immediately after Record command is issued.
P/N:PM0689
REV. 1.0.3, DEC. 13, 1999

MX93032
6. OGM Deletion
By setting bit 5 (Annc Del) to 1 on this command, the HOST can choose to delete the old OGM before recording a new
one. If that bit is cleared to 0, the old OGM is not deleted until the new OGM recording is completed. With this option,
the new OGM recording can be aborted without losing the old OGM by issuing Mark Fail (bit 11) on Record command.
7. New/Old Select
By setting New/Old Select (bit 6), the HOST can decide which condition a new message will be changed to an old one.
There are two options. When this bit is set to 1, the new message that has been played (even not played end) is
regarded as an old message. If this bit is cleared to 0, the new message that has been played end is regarded as an
old one.
8. Tail Cut Unit
By setting Tail Cut Unit (bit 7) to 1, the HOST can choose the tail cut unit length to be 200 ms. If this bit is cleared to
0, the unit length is 400 ms.
9. Old Mark Set
By setting Old Mark Set (bit 8) to 1, the HOST can disable that new messages change to be old ones even though
they have been played (end). If this bit is cleared to 0, new to old change will be enabled and the change criterion is
according to the setting of New/Old Select bit (bit 6).
GET RECORD MESSAGE INFORMATION
In this mode, there are 10 request codes for the control program to get the related information about a specified
message.
Given the Msg ID (bit 0-6) and New Msg flag (bit 7), the MX93032-M1 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 MX93032-M1 timer has been set before
with Set Current Time command. Otherwise, the response word is 0.
7. Get the message ICM/MEMO 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 check if the specified message has been tagged a Del Mark
(response word = 1) or not (response word = 0).
9. Get the message new/old status. (Request Code = 1000). To check if the specified message has been tagged an
Old Mark (response word = 1) or not (response word = 0). A new message will be tagged an Old Mark when it has
been played/played end and changes to old messages as Real Del command is issued.
10.Get the OGM existing status (Request Code = 1111). To check if the specified OGM exists (response word = 1) or
not (response word = 0). Msg ID could only range from 127 to 121.
11.To get link index data(Request Code=1001),refer to mode7
12.To set the Msg. ID for reading/writing Link-index-data.(Request Code=1010)

VOICE PROMPT
In this mode the MX93032-M1 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 voice prompt ROM or Flash memory, are provided
by the MX93032-M1 and pronounced using the speech decompression algorithm. The HOST can pause the playback
by setting Pause (bit 8) to 1 or resume from pause by clearing Pause 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 MX93032-M1 keeps monitoring the
line signal and sends the results in response word to the control program.
The MX93032-M1 will terminate Voice Prompt mode when Stop bit is set to 1 on Voice Prompt command.
SPEAKERPHONE
Regarding to speakerphone related function is comprised of three types which are parameter setting, DTMF/Tone
generation and free run. Two Codecs are necessary for speakerphone operation. One Codec labeled as Codec 1 is
used for microphone and speaker, and the other labeled as Codec 2 is used for telephone line input and output. In this
mode, there are seven functions whose detail will be given as follows:
1. Free run which performs both filtering operation and updating operation on LEC and AEC one time for each Codec
interrupt triggered (Request Code = 0x0000)
2. Setting the gain for DTMF/Tone generation (Request Code = 0x0001)
3. Generating DTMF/Tone according to pre-defined table (Request Code = 0x0010)
4. Setting both the echo return-loss on speaker side (ERL_AEC) and echo return loss on line side (ERL_LEC)
(Request Code = 0x0100)
5. The T/R and R/T ratio are used to decide which side is speaking by comparing the transmitting and receiving
energy.(Request Code=0x0110)
6. Set the volume gains to control the speaker out and line out signal levels(Request Code=0x1000)
7. The loop attenuation is to control the total receive and transmit attenuators (Request Code = 0x1001)
8. setting the tone table which require 3 steps : Index set, Freq_Lo set and Freq_Hi set.
PERSONAL MAIL
Five functions 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 messages and retrieving message time. Each mailbox manages its own messages and Msg IDs.
Make sure to set the desired mailbox before issuing the message related commands such as Record, Play, Delete
Message and Get Record Message Information.
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.
3. Set the digital loop back control
The HOST can enable or disable the DSP digital loop back path in Record or Line Monitor operation. By setting Loop
Back bit to 1, the loop back path is disabled and the signal received from the codec input will not be transmitted back
P/N:PM0689
REV. 1.0.3, DEC. 13, 1999
24
MX93032
to the codec output. When this bit is cleared to 0, loop back is enabled and the received signal will be transmitted back
to the codec output. The default status is the latter.
4. Set the output level
The HOST can set the level difference between the output (playback) speech and the corresponding input (recordedin) speech. By setting the Output Level bit to 1, the output speech level is equal to the input speech level, and clearing
this bit to 0, the output speech level is about 5dB less than the input speech level. The default status is the latter.
5. Set the codec data format
The HOST can select one of two Codec data formats by setting the Codec Format bit. When Codec Format is cleared
to 0, 8-bit m-law data format is selected, and set to 1, 16-bit linear data format is enabled. At present, MXIC’s Codec
family provide both m-law and linear formats, and the latter is suggested because of the better speech quality. The
default format is 8-bit m-law.
6. Set 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.
7. Set Telephone Data Configuration
This command should be issued before Aflash initialization.
CAS Detection
The MX93032-M1 provides 2 output modes for CAS detection, which are continuous response and one time response.
For continuous response, the MX93032-M1 will respond CAS detected after 45± 5ms since CAS occurs in CPE.
Regarding to response one time, the information of CAS detected will be responded after both the CAS is disappeared
on the line and the duration for CAS appearance between 45ms to 95 ms.
FSK Detection
The output of FSK detector can be divided into two mode which are Raw data mode and Cooked data buffer. The
buffer length for Raw data mode and Cooked Data mode are 8 bytes and 60 bytes long, respectively. For Raw data
mode, the data ready bit will be set on one bytes data ,in which start bit and stop bit are not included, received
correctly. If the host’s speed can not catch up the FSK baudrate, buffer overflow will occur. Therefore, when the serial
interface is adopted, we do not recommend to select Raw data mode to receive FSK data. Cooked data mode
concerned, the data ready bit will be set after all of the data, in which checksum is included, received. During the
operation for Cooked data mode, the second data byte following the mark data will be considered as the total data
length, the other data will not be recognized by MX93032-M1.
LINKAGE BETWEEN CID DATA AND VOICE MESSAGE
1. Set the link index which can be also considered as CID data number (Request code = 0x7500 | link index)
2. Get the link index (Request code = 0xA900 | msg_no)
3. write the link index specified by 0x7500 into message (Request code = 0xAA00 | msg_no)

MX93032
TELEPHONE DATA
In this mode the HOST can write/read telephone or user-assigned data to/from the FLASH with the sequence of
telephone data command as follows :
1. Write Telephone Data
The first command defines the telephone record ID (bit 0-7) and set bit 11, 10 to 0, 0.
Following command specifies the one-byte data to be stored under that ID.
While the current record ID is full, the MX93032-M1 BIOS will show the status in response word (bit 0, Full).
The MX93032-M1 BIOS will terminate Telephone Data mode when Stop (bit 9) is set to 1 on Telephone Data command.
2. Read Telephone Data
The first command defines the telephone record ID (bit 0-7) and set bit 11, 10 to 0, 1. The telephone data will be put
on the response word. Following command puts the one-byte data on the response word to the control program.
The response word contains the byte-data (bit 0-7) and Read End (bit 8). When the Read End bit is 1, the byte-data is
invalid.
The MX93032-M1 BIOS will terminate Telephone Data mode when Stop (bit 9) is set to 1 on Telephone Data command.
If host want to write/read more than 2 Tel. Record IDs at the same time, Before writing/reading an new Tel. ID, host
should set STOP bit to 1 for the current Tel. ID.

1. The tone frequency whose index is specified form 10000 to 11111 can be stored into the ROM space with starting
address specified by the label "TONE_TAB". At the same time, the label "TONE_TAB" should be declared as
global.
2. The legal index values for dual tone are just from 10000 to 10111. For dual tone mode, it will catch the frequency
specified by both the index and index+8.

APPENDIX A : CID TEST REPORT BASED ON SR-3004
1.
Type 1 Testing
1.1
Testing Items
A list of parameters to test based on SR-3004 are divided into two categories: Transmission tests and Message
Format tests. Transmission tests vary electrical properties of signals to identify when and where CPE fails to detect.
The Message Format tests vary the content and formatting of the data message. The following tests assumes that
Transmission testing is independent of Message Format testing. The FSK mode provided on the MX93032-M1 is just
responsible to decode the physical layer and data link layer. Therefore, Only transmission test associated with the
MX93032-M1 will be given. For message format tests, it should be tested by "system manufacturers" depending on
the their interesting region.

TYPE II TESTING
The Type 2 CPE requires all of the same conformance test as Type 1 CPE in addition to "CAS detector performance”
2.1
CAS Detector Performance
There are three types of tests to perform for CAS detector performance:
Signal Recognition Tolerance ( without speech )
Talk off ( false detection due to speech )
Talk Down (missed detection due to interference from speech )
2.1.1

Various combinations of the above parameter values will be tested by sending 1000 CAS tones to the CPE at a rate
not exceeding 2 per second. The various parameter combinations are broken into three groups described as follows.
Each test combination requires 34 minutes to complete with 1000 burst at a 2 second interval.
Group 1 consists of all the parameters at their nominal value.
Group 2 sets each parameter ( one at a time) to its extreme values, while the remaining parameters remain
at their nominal value.
Group 3 sets all parameters to 90% of its extreme value. All of the possible parameter combinations are
tested.

Talkdown Condition 1 -- the combination of average signal level (-22 dBm /tone) and average speech level (-19 dBm).
At least 99.5% of the signals sent should be received correctly using derated missed rate.
Talkdown Condition 2 -- the weight average of the worst one percent of the 72 combinations. At least 93% of the signal
sent should be received correctly using the derated missed rate.
Talkdown Condition 3 -- the weighted average of all of the 72 combinations. At least 99.5% of the signal should be
received correctly using derated missed rate.\

Talkoff Condition 1 : the combination of average near-end level (-19 dBm) and the average far end level (-28 dBm).
This talkoff rate should be less than 1 in 45 hours
Talkoff Condition 2 : the weighted average of the worst one percent of the 63 combinations. The talkoff rate should be
less than 1 in 10 hours.
Talkoff Condition 3 : the weighted average of all of the 63 combinations. The talk off rate should be less than 1 in 35
hours.
Tested Result :
Condition 1 (nominal ) : 1 hit per 38.4 hours
Condition 2 (worst 1 %) : 1 hit per 16.79 hours
Condition 3 (global)
: 1 hit per 35.73 hours
( Spec. >= 45 hours)
( Spec. >= 10 hours)
( Spec. >= 35 hours)
3. Recommendation:
All of the test results corresponding to talkdown given above are obtained by configuring our demo board to "Adjunct
Model". That is, our demo board was connected directly to the Tip and Ring on which the far end speech and far end
CAS has been mixed. Therefore, there is no way to tell speech signal from the CAS on that testing configuration
adopted by us. For practical application, Near end speech instead of far end speech should occur on talkdown test. If
the mixed signal captured from tip and ring can be subtracted from the source signal captured from the near end
speech with proper gain. Then the SNR of resultant signal will be highly improved on adjusting the impedance match
between CPE and SPCS adequately. According to our experience, if the quantity of the echo canceller can excess 6
dB, the performance of CAS detector embedded on 93032-M1 will meet the Bellcore specification for talkdown. The
feature of echo canceller will be inherently possessed by phone mode, there will be additional circuit to implement
echo canceller for adjunct model.

APPENDIX B : OPERATION GUIDE FOR THE 93032-M1 DEMO BOARD
1.
INTRODUCTION:
The evaluation board (EVB) is provided by Macronix is to demonstrate both Digital speakerphone, Caller
ID and DAM functions. There are four parts in EVB:
1.
Main Module with label "A001-BD-0038A"
2.
DSP Module with label "A001-BD-0031B"
3.
DAA Module with label "MSP-PCB-010A"
4.
MCU Module with label "A001-BD-0040A"
The key pad is arranged into six kinds of definitions:
1. DAM mode keys: The power on default key function to demo DAM record/play/etc functions.
2. Speakerphone mode keys: Press "spk phone on" in DAM mode to enter speakerphone mode.
User can dial DTMF, set loudspeaker / lineout volume or mute line-out signal.
3. Speaker test mode keys : Press "test mode" key in speakerphone mode for 1 second to enter
this mode which allows user to set all the speakerphone BIOS parameters through key pad.
4. CPE Alerting Signal (CAS) test : Press "CAS Test" and last for 1 second in DAM mode to enter
CAS test mode. During this mode , the number of CAS signal received from Tip and Ring will be
counted and represented on LCD display.
5. Caller ID TypeII Test mode: Press "CAS Test" within 1 second in DAM mode to come into Caller
ID Type II Test mode. After coming into this mode, 93032-M1 will monitor line and detect the
CAS signal presented on line. The DTMF will be sent out as the CAS was found, following the
FSK will be decoded and showed on LCD.
6. Encoding mode selection : Press "Enc. Select" in DAM mode to switch the encoding mode
either 4.8 k or 12.8 k.
7. Flash Re-initialization : Press "Flash Re-Init." in DAM mode to perform FLAH Re-Initialization
