26.6.7 Synchronization
Due to asynchronicity between the main clock domain and the peripheral clock domains, some registers need to be synchronized when written or read.
The following registers are synchronized when written:
- Watchdog Control A register (CTRLA)
- Watchdog Clear register (CLEAR)
Required write-synchronization is denoted by the "Write-Synchronized" property in the register description.
Required read-synchronization is denoted by the "Read-Synchronized" property in the register description.
