18.5.8 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)
  • Read Request register (READREQ)
  • Status register (STATUS)
  • Debug register (DBGCTRL)
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.
