The watchdog timer (WDT) driver includes two layers: the hardware abstraction layer (HAL) and the driver layer (DRV).

The hardware abstraction layer provides basic APIs for accessing the registers of the WDT. All functions in this layer are implemented as inline functions. See the API documentation for the WDT HAL for details.

The driver layer provides APIs on a higher level than the HAL. See the API documentation for the WDT driver for details.

The WDT Example provides sample code that you can use to quickly get started.
