LGRP0
Interpolation Filter Group Delay
LGRP1
These bits are used to select the number of input samples to be stored in the data buffer before the re-sampler
starts to process the data. This has a direct impact on the group delay or latency of the interpolation filter.

DECIMATION FILTER OPERATION
Decimation filter enabled. (default)
(Must be used when fsOUT is less than or equal to fsIN.)
Direct downsampling enabled without filtering.
(May be enabled when fsOUT is greater than fsIN.)
