30.5.7 Register Access Protection
All registers with write-access can be write-protected optionally by the Peripheral Access Controller (PAC), except the following registers:
- Interrupt Flag Status and Clear (INTFLAG) register
- Data Buffer (DATABUF) register
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
