Acknowledge enable.
9 AE 0: The acknowledge flag is disabled for the particular filter
1: The acknowledge flag is enabled for the particular filter
Filter enable.
8 FEN 0: The filter is disabled and no data is produced
1: The filter is enabled and data are produced in the sinc filter and/or integrator
Oversampling ratio. The actual rate is SOSR + 1.
7 – 0 SOSR7 – SOSR0 These bits set the oversampling ratio of the filter.
0xFF represents an oversampling ratio of 256.
