GFM Multiplier Data Processing.
Writing of a value here registers the data for processing. Processed data is regis-
tered into the same register with single CLK_SYS cycle delay. Read from this reg-
ister reads the processed multiplied data. The register GFM_CONST must be
written before GFM_DATA is written.
GFM Multiplier Constant Register.
This is the constant by which the GFM_DATA is multiplied by. It has to be written
prior to GFM_DATA.
