cleared when ARM in DBGC1 is written to a 1 or on any write to this register.
0 Trigger A did not match
1 Trigger A match
Trigger B Match Flag — The BF bit indicates if trigger B match condition was met since arming.This bit is
cleared when ARM in DBGC1 is written to a 1 or on any write to this register.
0 Trigger B did not match
1 Trigger B match
Comparator C Match Flag — The CF bit indicates if comparator C match condition was met since arming.This
bit is cleared when ARM in DBGC1 is written to a 1 or on any write to this register.
