This does not switch the radio to mono or stereo. This depends on the RF input level as shown under ‘mono stereo blend’ or ‘mono
stereo switched’.

Description
1 = left audio output is hard muted and the radio is forced to
mono
0 = not muted
1 = right audio output is hard muted and the radio is forced to
mono
0 = not muted
AFM disable bit. When AFM = 1 and TM = 1 during the tuning
algorithm, AFM is disabled
see
1 = MMBS mode on
0 = MMBS mode off
tuning programming error indicator when TM = 1
1 = RFAGC off
0 = RFAGC on
when TM = 1, INTX follows bit INTCTRL; when TM = 0, then
INTCTRL = 1 generates an interrupt on INTX
not used
SNCLEV switches the starting point mono/stereo blending
1 = software Test mode and software port outputs according
to
0 = normal operation
test bits;
pins SWPORT and INTX
Description
1 = PLL locked is detected
0 = PLL is not locked
1 = pilot detected
0 = no pilot
not used
1 = level hysteresis is large
0 = level hysteresis is small
