The TDR, shown in
corresponds with the ABHR/ABLR/AATR, PBR/PBMR, and DBR/DBMR registers within the debug
module. The TDR controls the actions taken under the defined conditions. Breakpoint logic may be
configured as a one- or two-level trigger. TDR[31–16] define the second-level trigger and bits 15–0 define
the first-level trigger.

PC breakpoint mask. A zero in a bit position causes the corresponding PBR bit to be compared to the
appropriate PC bit. Set PBMR bits cause PBR bits to be ignored.
