25.5.8 Register Access Protection
All registers with write-access can be write-protected optionally by the Peripheral Access Controller (PAC), except for the following registers:
- Interrupt Pending register (INTPEND)
- Channel ID register (CHID)
- Channel Interrupt Flag Status and Clear register (CHINTFLAG)
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.
