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)
- Read Request register (READREQ)

write-protection is indicated by the "PAC Write-Protection" property in the register

Write-protection does not apply for accesses through an external
debugger.
