ISD-T360SB
GMT
Returns the 16-bit tag associated with the current message. If the current message is undefined,
ERR_INVALID is reported.
Example
GNM
Returns the number of messages whose message tags match the tag_ref parameter. Only bits set in
tag_mask are compared, a match is considered successful if:
The tag_ref and tag_mask parameters are each two bytes; the return value is also two bytes long.
See “Message Tag” on page 2-3 for a description of message-tag encoding. If tag_mask = 0, the total
number of all existing messages is returned, regardless of the tag_ref value.
Example
GSW
Returns the 2-byte status word.
STATUS WORD
The VoiceDSP processor has a 16-bit status word to indicate events that occur during normal operation.
The VoiceDSP processor asserts the MWRQST signal (clears to 0), to indicate a change in the status word.
This signal remains active until the VoiceDSP processor receives a GSW command.

Description:
message tag and tag_mask = tag_ref and tag_mask
where and is a bitwise AND operation.
Microcontroller
VoiceDSP
Get the current message tag.
In a system where the message tag is encoded as described in the DMS command, the
VoiceDSP processor return value indicates that the message is a new ICM in mailbox Number
6.
Microcontroller
VoiceDSP
Get the number of messages which have bit 0 cleared, and bit 1 set, in their message tags.
VoiceDSP processor responds that there are five messages which satisfy the request.
