35.5.8 Register Access Protection
Registers with write-access can be optionally write-protected by the Peripheral Access Controller (PAC), except for the following:
- Interrupt Flag Status and Clear register (INTFLAG)
- Status register (STATUS)
- Count register (COUNT)
- Period and Period Buffer registers (PER, PERBUF)
- Compare/Capture Value registers and Compare/Capture Value Buffer registers (CCx, CCBUFx)
Note: Optional
write-protection is indicated by the "PAC Write-Protection" property in the register
description.
Write-protection does not apply for accesses through an external
debugger.
