25.7 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 are optionally write protected by the PAC. Optional PAC write protection is denoted by the PAC Write-Protection property in each individual register description. See Register Access Protection from Related Links.

Some registers are enable protected, meaning they can only be written when the peripheral is disabled. Enable protection is denoted by the Enable-Protected property in each individual register description.
