OPERATION MODES

The FCOP operation modes are controlled by the FOM[0:1] bits in the FCSR as described
in Section 12.4.6.2. In each mode, the FDCM bit in FCSR selects between no decimation
or decimation by two. The following sections describe the operation of FCOP in each
mode, either with no decimation or with decimation by two. The description includes:
equation of the implemented filter, initialization and processing steps, data and
coefficients input scheme, output data scheme.
