Description
Filter Count. An initial count is loaded into the FILTER_COUNT via the
FILTER_AMOUNT register. Direct access to the counter’s state is provided via the
FILTER_COUNT register and may be read at any time to determine the current value
of the counter. The FILTER_COUNT register may also be written to at any time,
thereby jamming the counter state forward or backward from the current count.
