DESCRIPTION
7
Not used. Set to logic 0.
6
STBA
Standby mode audio processing. 0 = audio processing active; 1 = audio processing
in standby mode (audio inputs and outputs at DC).
5
AFUM
Enables AF update mute. 0 = AF update mute disabled; 1 = AF update mute enabled
(controlled by AFSAMP and AFHOLD input).
4
AFUH
AF update hold function. 0 = disable, the weak signal processing hold is controlled by
the AFHOLD input only; 1 = hold. This is equal to taking the AFHOLD input LOW. The
bit is reset to 0, when AFHOLD input is set to LOW (i.e. at AF update or preset change).
3
RMUT
Radio signal mute. 0 = no mute; 1 = mute with 1 ms ASI slope at start and stop.
