Stop Record/Playback
Playback and Record can be stopped using the Idle command. However, this stops both Playback and Record. To
stop Playback without stopping Record or to stop Record without stopping Playback, the Stop command may be
used. There are three Stop commands, two for Playback and one for Record:
Stop Record:
Command: 5120H
Status:
5120H
Stop Playback:
Command: 5220H
Status: 5220H
Stop Playback and flush CODEC output buffer (immediate stop) recommended.
Command: 5221H
Status:
5221H
In PLAYBACK mode, Stop Playback causes the CT8022 to enter IDLE mode. In full-duplex speech mode, this
command changes the CT8022 state to RECORD.
In RECORD mode, Stop Record causes the CT8022 to enter IDLE mode. In full-duplex speech mode, this
command changes the CT8022 state to PLAYBACK.
Use Stop Playback with flush option to terminate playback if the record channel remains active after playback was
completed.
When operating playback only or record only, it is recommended that the Idle command be used to stop
playback/record.
