18.5.7 Register Access Protection

All registers with write-access can be write-protected optionally by the Peripheral Access Controller (PAC), except for the following register: Interrupt Flag Status and Clear register (INTFLAG).

Optional write-protection by the Peripheral Access Controller (PAC) is denoted by the "PAC Write- Protection" property in each individual register description. PAC write-protection does not apply to accesses through an external debugger.
