ISD-T360SB
SLC
Configures the VoiceDSP to activate/deactivate channel 1. The activation of channel 1 is used to enable
the conversation recording feature. When activating this feature, the VoiceDSP sums channel 0 and
channel 1 during the record command and then compresses the sum. When playing the message, it is
decompressed and broadcasted to the active channels as set by this command. Note that channel 0
is always active and is used as the default line channel.
Use the following parameter values to activate the channels:
Example
SMSG
Sets the message pointer to num_of_pages x 32 bytes from the beginning of the current message data.
If the VoiceDSP processor was in the IDLE state, the command opens the current message and switches
the VoiceDSP processor to the MSG_OPEN state. The microcontroller must issue an S command to close
the message, and switch the VoiceDSP processor to the IDLE state.
If num_of_pages x 32 is greater than the message length, EV_NORMAL_END is set in the status word, the
message pointer is set to the end of the message, and the VoiceDSP processor switches to the IDLE state.
If the current message is undefined, ERR_INVALID is reported.
Example
SMT
Sets the tag of the current message. The 2-byte message_tag can be used to implement mailbox func-
tions by including the mailbox number in the tag, or to handle old and new messages differently by using
one bit in the tag to mark the message as old or new. See “Message Tag” on page 2-3.
To change the message tag, you should first get the tag using the GMT command, read the tag, modify
it, and write it back.
