30.3.1 Initialization

The following steps are recommended to initialize the SWDT for basic operation:

Configure the Reset Value of the SWDT by writing to the RESET register
Configure the WINDOW register. As shown in the block diagram above, this value is compared with CNT to determine when the window is open for clearing the counter.
Enable the SWDT by simultaneously writing a ‘1’ to the ENABLE bit and either a ‘0’ or a ‘1’ to the MODE selection bit (to choose count mode) in the CTRLA register
