42.5.6 Register Access Protection

All registers with write access can be write-protected optionally by the Peripheral Access Controller (PAC). Refer to the Chapter 15 Peripheral Access Controller (PAC) for additional information.

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.
