3.6.1.7 Windowed/Filtered Mode (7)
Windowed/filtered mode is the most complex mode of operation for the comparator
block because it uses both windowing and filtering features. It also has the highest
latency of any mode. This can be approximated: up to 1 peripheral clock synchronization
in the window function + ((FILTER_CNT X FILT_PER) + 1) X peripheral clock for the
filter function.
When any windowed mode is active, COUTA is clocked by the peripheral clock
whenever WINDOW = 1. The last latched value is held when WINDOW = 0.
