19.4.3.2
A breakpoint request to the CPU can be created if BKCEN in DBGC2 is set. Breakpoints based on a
successful comparator C match can be accomplished regardless of the mode of operation for comparator
A or B, and do not affect the status of the ARM bit. TAGC in DBGC2 is used to select either tagged or
forced breakpoint requests for comparator C. Breakpoints based on comparator C are disabled in LOOP1
mode.
19.5
The DBG module is disabled after reset.
The DBG module cannot cause a MCU reset.
19.6
The DBG contains one interrupt source. If a breakpoint is requested and BDM in DBGC2 is cleared, an
SWI interrupt will be generated.

Breakpoint Based on Comparator C
Because breakpoints cannot be disabled when the DBG is armed, one must
be careful to avoid an “infinite breakpoint loop” when using tagged-type C
breakpoints while the DBG is armed. If BDM breakpoints are selected,
executing a TRACE1 instruction before the GO instruction is the
recommended way to avoid re-triggering a breakpoint if one does not wish
to de-arm the DBG. If SWI breakpoints are selected, disarming the DBG in
the SWI interrupt service routine is the recommended way to avoid
re-triggering a breakpoint.
