Displays (in two’s complement format) the FM (or AM) DC offset level after demodulation on
channel 1 (and removed automatically).
In FM mode, the DC offset value gives a direct value of the carrier frequency offset which is
used to compensate the DCO with the CAROFFSET1 value in the event of an out-of-standard
offset. The range and the resolution depend upon the FM bandwidth programmed defined in
register BCOEFF1. See
