32.8.1.3 Sampled, Non-Filtered Mode (#s 3A & 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. In #3A, the clock to
filter block is externally derived while in #3B, the clock to filter block is internally
derived.
The comparator filter has no other function than sample/hold of the comparator output in
this mode (# 3B).
