3.6.1.3 Sampled, Non-Filtered Mode (3A and 3B)
In sampled, non-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,
Non-Filtered (3B) is in how the clock to the filter block is derived.
The comparator filter has no other function than sample/hold of the comparator output in
this mode.
