9.3. About the FPB

The FPB implements hardware breakpoints.

The FPB can be configured during implementation to provide either four or eight instruction comparators. You can configure each comparator individually to return a BKPT instruction to the processor on a match, to provide hardware breakpoint capability.

The FPB does not support Flash patching. The FP_REMAP register is not implemented and is RAZ/WI.
