• Manufacturer Part Number: ISD-T360
• Description: VoiceDSP Digital Speech Processor with Master/Slave, Full-Duplex Speakerphone, Multiple Flash and ARAM/DRAM Support
• Manufacturer: ETC [List of Unclassifed Manufacturers]

Example
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.
NOTE
Example
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.
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
Example of a typical recording session:
• (ICM) The microcontroller detects the first ring.
• (ICM, OGM, memo) The microcontroller sends the R command.

Byte sequence:
Description:
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.
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.
