Register Description

Registers can be 8, 16, or 32 bits wide. Atomic 8-, 16-, and 32-bit accesses are supported. In addition, the 8-bit quarters and 16-bit halves of a 32-bit register and the 8-bit halves of a 16-bit register can be accessed directly.

All registers with write-access can be write-protected optionally by the peripheral access controller (PAC). Optional Write-Protection by the Peripheral Access Controller (PAC) is denoted by the "PAC Write-Protection" property in the register description. Write-protection does not apply to accesses through an external debugger.

On SAM L11 devices, this peripheral has different access permissions depending on PAC Security Attribution (Secure or Non-Secure): Refer to Peripherals Security Attribution for more information.
