CMP Functional Description
The only difference in operation between Sampled, Non-Filtered (# 3B) and Sampled,
Filtered (# 4B) is that CR0[FILTER_CNT] is now greater than 1, which activates filter
operation.
32.8.1.5 Windowed Mode (#s 5A & 5B)
The following figure illustrates comparator operation in the windowed mode, ignoring
latency of the analog comparator, polarity select and Window Control block. It also
assumes that the Polarity Select is set to "non-inverting". Note that the analog comparator
output is passed to COUTA only when the WINDOW signal is high.
In actual operation, COUTA may lag the analog inputs by up to one bus clock cycle plus
the combinational path delay through the comparator and polarity select logic.
