The device includes one instance of the 32-bit watchdog timer: WD_TIMER2.
The watchdog timer is an upward counter capable of generating a pulse on the reset pin and an interrupt to the device system modules following an overflow condition. The WD_TIMER2 timer serves resets to the PRCM module (its interrupt outputs are unused).
WD_TIMER2 is located in the PD_WKUPAON power domain, and can run when the device is in lowest power state (all power domains are off except always-on (AON) and WKUP).
The watchdog timer can be accessed, loaded, and cleared by registers through the L4_WKUP interface. The watchdog timer has the 32-kHz clock for its timer clock input. WD_TIMER2 directly generates a warm reset condition on overflow.
WD_TIMER2 connects to a single target agent port on the L4_WKUP interconnect.
The main features of the watchdog timer controllers are:
