32.5.8 Register Access Protection

Registers with write access can be write-protected optionally by the Peripheral Access Controller (PAC).

PAC write protection is not available for the following registers:

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

Optional PAC write protection is denoted by the "PAC Write-Protection" property in each individual register description.

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