Values in
AFF[1:0] (Average Filter Frequency) define the average filter cut-off frequency if the AFFC bit is set.
If AFFC is reset, the average filter frequency is directly defined by bits DR[1:0], as shown in
If AFFC is set, AFF[1:0] allow the overall receiver sensitivity to be improved by reducing the average
filter cut-off frequency. The typical preamble duration of three Manchester zeroes or ones at the data rate
must then be increased, as shown in
