41.8 Register Description - 8-Bit Mode

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.

Some registers are synchronized when read and/or written. Synchronization is denoted by the Write-Synchronized or the Read-Synchronized property in each individual register description.

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.
