Message Cueing
Message cueing (MC) allows the user to skip through messages, without knowing the actual physical
location of the messages. It will stop when an EOM marker is reached. Then, the internal address
counter will point to the next message. Also, it will enter into OVF condition when it reaches the end of
memory. In this mode, the messages are skipped 1,600 times faster than the normal playback
mode.
Power-Up Sequence
The ISD4003 will be ready for an operation after power-up command is sent and followed by the T
timing (25 ms for 8 KHz sampling rate). Refer to the AC timing table for other T
to different sampling rates.
The following sequences are recommended for optimized Record and Playback operations.
Record Mode
For 3 & 4), please refer to Apps Brief 39A: recorded pop elimination in the ISD4000 series.
For 5.a), the device will start recording at address xx and will generate an interrupt when an overflow
(end of memory array) is reached, if no STOP command is sent before that. Then, it will automatic
stop recording operation.
Playback Mode
For 3.a), the device will start playback at address xx and it will generate an interrupt when an EOM or
OVF is reached. It will then stop playback operation.
