After AF update sampling the USN and WAM read value is held (indicated by IFCM = 10)
for easy I
The USN and WAM data hold is released after I

Description
ultrasonic noise detector; this value indicates the USN content of the
MPX audio signal; see
wideband AM detector; this value indicates the WAM content of the
LEVEL voltage; see
Description
modulation detector; this value indicates the audio modulation; see
Table 15
FM offset detector; a read value of 31 indicates offset detection. The
offset detector is part of the FM bandwidth control algorithm and detects
adjacent channel breakthrough.
VU-meter; when an external audio source is selected and VU-meter read
is active (see subaddress 17h; see
input level (RMS) between 0 V and 2 V; see
stereo indicator; this bit indicates if a stereo pilot signal has been
detected
Tuning action state; state machine information. The signal TAS informs
about internal control functions of the tuner action state machine. This
way the progress of tuner actions can be monitored by the
microcontroller.

MOD2
FM between 0 kHz and 150 kHz FM deviation
AM between 0 % and 200 % modulation
0 = no pilot signal detected
1 = pilot signal is detected and the FM stereo decoder is activated
00 = inactive
01 = starting mute
10 = PLL tuning
11 = tuning ready with mute active
