Not used. Set to logic 0.
Test. TST[3:0] = 0000: normal operation.
Not used. Set to logic 0.
Not used. Set to logic 0.
Standby mode audio processing. 0 = audio processing active; 1 = audio processing
in standby mode (audio inputs and outputs at DC).
Enables AF update mute. 0 = AF update mute disabled; 1 = AF update mute enabled
(controlled by AFSAMP and AFHOLD input).
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).
Radio signal mute. 0 = no mute; 1 = mute with 1 ms ASI slope at start and stop.
