Functional Description
3.6.1.4 Sampled, Filtered Mode (4A and 4B)
In sampled, filtered mode, the analog comparator block is powered and active. The path
from analog inputs to COUTA is combinational (unclocked). Windowing control is
completely bypassed. COUTA is sampled whenever a rising edge is detected on the filter
block clock input.
The only difference in operation between Sampled, Non-Filtered (3A) and Sampled,
Filtered (4A) is that FILTER_CNT is now greater than 1, which activates filter operation.
