Standby mode RDS processing. 0 = RDS processing active; 1 = RDS processing in
standby mode (RDS off, RDS outputs LOW).
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.
Not used. Set to logic 0.
Fast level detector time constants. 0 = slow level detector time constants are used;
1 = fast level detector time constants are used. See Table 25.
Attack bound of the MPH and LEV detector. 0 = detectors are unbounded; 1 = range
of the MPH and LEV detector are limited in their range for immediate start of attack. In
AM mode the detectors are always unbounded.
FM stereo channel separation (high frequency). See Table 21.
FM stereo channel separation and adjustment. See Table 22.
Not used. Set to logic 0.
