27.5.5 Register Access Protection
All registers with write-access are optionally write-protected by the Peripheral Access Controller (PAC), except the following registers:
- Interrupt Flag Status and Clear register (INTFLAG)
- Status register (STATUS)
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. Refer to the PAC - Peripheral Access Controller
