D_AGC_ERR_LIM
R/W
With D_AGC_ERR_LIM the digital IF AGC
error slope is limited. This can improve
performance under the presence of e.g.
impulsive noise that can confuse the AGC
detector.

This determines the digital IF AGC forced value
and is a ‘don’t care’ if D_FORCE is LOW. The
format is twos complement. The default is 67h,
which equals 0 dB internal gain. In the following
