23  * TI CC13xx/CC26xx watchdog is a 32-bit timer that runs on the MCU clock
30  * The watchdog will issue reset only on second in turn time-out (if the timer
31  * or the interrupt aren't reset after the first time-out). By default, regular
32  * interrupt is generated but platform supports also NMI (can be enabled by
33  * setting the `interrupt-nmi` boolean DT property).
