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.

Some registers can be write-protected optionally by the Peripheral Access Controller (PAC). This is denoted by the property "PAC Write-Protection" in each individual register description. Refer to the Register Access Protection for details.

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.
