23.5.7 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 Flag Clear and Status register (INTFLAG)
  • Status register (STATUS)
  • Data register (DATA)
  • Address register (ADDR)

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.
