Registers with write-access can be optionally write-protected by
the Peripheral Access Controller (PAC), except for the following:
- Interrupt Flag (INTFLAG) register
- Channel Pending Interrupt (INTPEND)
- Channel n Interrupt Flag Status and
Clear (CHINTFLAGn)
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.
