28.4.3 Register Access Protection

All registers with write-access are optionally write-protected by the Peripheral Access Controller (PAC), except the following registers:

• Interrupt Flag Status and Clear (INTFLAG) register
• Status (STATUS) register.

Write-protection is denoted by the Write-Protected property in the register description.

Write-protection does not apply to accesses through an external debugger. Refer to the Peripheral Access Controller chapter for details.
