BIT SYMBOL DESCRIPTION
7 STBR Standby mode RDS processing. 0 = RDS processing active; 1 = RDS processing in
standby mode (RDS off, RDS outputs LOW).
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.
2 − Not used. Set to logic 0.
1 LETF Fast level detector time constants. 0 = slow level detector time constants are used;
1 = fast level detector time constants are used. See Table 25.
0 ATTB 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.
