WMSG
Writes 32 bytes of data to the current position of the message pointer, and advances the message
pointer by 32 bytes.
Write Message data
If the VoiceDSP processor is in the IDLE state, the command opens the current message, switches the
VoiceDSP processor to the MSG_OPEN state, sets the message pointer to the beginning of the mes-
sage data, and writes the 32 bytes of data.
To add data at the end of an existing message, issue the SMSG command to the last page of the mes-
sage. Issue the WMSG command with a buffer consisting of 32 FF bytes (this has no effect on the cur-
rent data in the page). A subsequent WMSG command adds a new block to the message, and writing
continues at the beginning of the new block.
The microcontroller must issue an S command to close the message and switch the VoiceDSP proces-
sor to the IDLE state.
NOTE
When updating an existing message, bits can only be cleared, but not set.
If the current message is undefined, ERR_INVALID is reported.
Example
