15.3 WDT Initialization and Configuration
To use the WDT, its peripheral clock must be enabled. The WDT is running off the infrastructure clock
sourced by the MCU PRCM module. The WDT is then configured using the following sequence:
1. Load the [WDT:LOAD] register with the desired timer load value.
2. If the Watchdog is configured to trigger system resets, set the [WDT:CTL:RESEN] bit.
3. Set the [WDT:CTL:INTEN] bit to enable the WDT.
4. Lock the WDT module using [WDT:LOCK].
