MX93032
LINE MONITOR
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 :

The MX93032-M1 will terminate Line Monitor mode when Stop bit is 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 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.
4. To set week, put the data in bit 0-7 and use request code (bit 8-11) 0011.
5. To set voice prompt configuration, put the selection data in bit 0-1 and use request code (bit 8-11) 0110.
6. To set silence threshold level, put the data in bit 0-3 and use request code (bit 8-11) 0111.
7. To set output port OPT0-7, put data in bit0-7(Request Code=0100)
8. To set codec MX93002 registers in bit10-8 and put data in bit0-7(Request Code=1xxx)
9. To write link index and data in bit0-7(Request Code=0101), refer to mode10 to specify Msg. ID.
