RES
Resume
Resumes the activity that was suspended by the PA, SB, or SF commands.
Example
RES
Byte sequence: Microcontroller
1D
VoiceDSP
1D
Description:
Resume playback which was suspended by either the PA, SF or SB command.
RMSG
Read Message
Returns 32 bytes of data from the current position of the message pointer, and advances the message
pointer by 32 bytes.
If the VoiceDSP processor was 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 returns the 32 bytes of data.
The microcontroller must issue an S command to close the message, and switch the VoiceDSP proces-
sor to the IDLE state.
If the current message is undefined, ERR_INVALID is reported.
Trying to read beyond the end of the message sets the EV_NORMAL_END event, and the VoiceDSP
processor switches to the IDLE state. In this case, the return value is undefined and should be ignored.

Description:
Read 32 bytes from the current message memory.
S
Stop
Stops execution of the current command and switches the VoiceDSP processor to the IDLE state. S
may be used to stop the execution of CMSG, SMSG, WMSG, RMSG and all asynchronous commands.
