AF — Trigger Match A Flag
AF is cleared at the start of a debug run and indicates whether a trigger match A condition was met
since arming.
1 = Comparator A match.
0 = Comparator A has not matched.
BF — Trigger Match B Flag
BF is cleared at the start of a debug run and indicates whether a trigger match B condition was met
since arming.
1 = Comparator B match.
0 = Comparator B has not matched.
