Field
Description
0–31 Integration Sum Value—The SUM_VALUE[31:0] field holds an unsigned number representing the sum of filtered
SUM_VALUE output values, continuously updated as the integration proceeds. The control of the integration sum is
determined by the register DECFILT_x_MXCR (see Section 28.2.2.3, Decimation Filter Module Extended
Configuration Register (DECFILT_x_MXCR)).

COUNT
Description
Integration Count Value—The COUNT field holds the count of filtered outputs integrated. The value is updated
only when register DECFILT_x_CINTVAL is read, to keep the coherency between the integration and count
values.
