go to Idle mode
go to Power-down mode
Go to Idle mode without completing the
current GOP/audio frame. This is intended for
use in cases similar to no video/audio input
present.
Enables SAA6752HS to time-out to Idle mode
if STOP to IDLE transition cannot be
completed (i.e. due to no video signal being
present). If a general error event is detected,
the SAA6752HS will automatically switch to
Idle mode via forced reconfigure.
