Example
PA
Byte sequence:
PDM
Switches the VoiceDSP processor to power-down mode (see “POWER-DOWN MODE” on page 1-4 for
details). Sending any command while in power-down mode resets the processor detectors, and re-
turns it to normal operation mode.
Go To Power-Down Mode
NOTE
If an event report is pending (MWRQST is active) and not processed by the microcontroller prior to
issuing the PDM command, the event is lost.
Example
PDM
Byte sequence:
R
Records a new message with message tag tag and compression rate compression_rate. The VoiceD-
SP processor state changes to RECORD. The R command continues execution until stopped by the S
command. Recording can be paused with the PA command, and can be resumed later with the RES
command.
Record tag compression_rate
If the memory becomes full, recording stops and EV_MEMFULL is set in the status word.
See “Message Tag” on page 2-3 for a description of message-tag encoding.
The compression rate may be defined as 0 for PCM recording or either 1, 3, 6 for compression rates 5.3
Kbits/sec, 9.9 Kbits/sec, 16.8 Kbits/sec respectively. See “ VCD” on page 2-10 for a description of the
compression algorithm.
NOTE
A time-and-day stamp is automatically attached to each message. Before using the R command
for the first time, use the SETD command. Failure to do so results in undefined values for the time-and-
day stamp.
Example of a typical recording session:
(ICM) The microcontroller detects the first ring.
(ICM, OGM, memo) The microcontroller sends the R command.
