Note 4: If the data matching functionality is not included during implementation it is not possible to set DATAVADDR0, DATAVADDR1, or DATAVMATCH. This means that the data matching functionality is not available in the implementation. Test the availability of data matching by writing and reading DATAVMATCH. If it is not settable then data matching is unavailable. Note 5: PC match is not recommended for watchpoints because it stops after the instruction. It mainly guards and triggers the ETM."]
