Development Support
TRG3:TRG2:TRG1:TRG0 — Select Trigger Mode
15.5.3.9 Debug Status Register (DBGS)
This is a read-only status register.
AF — Trigger Match A Flag
BF — Trigger Match B Flag
256
Selects one of nine triggering modes
AF is cleared at the start of a debug run and indicates whether a trigger match A condition was met
since arming.
BF is cleared at the start of a debug run and indicates whether a trigger match B condition was met
since arming.
1 = Comparator A match.
0 = Comparator A has not matched.
1 = Comparator B match.
0 = Comparator B has not matched.
