Each device contains two watchdogs: CPU-watchdog that monitors the core and NMI-watchdog that is a missing clock-detect circuit. The user software must regularly reset the CPU-watchdog counter within a certain time frame; otherwise, the CPU-watchdog generates a reset to the processor. The CPU-watchdog can be disabled if necessary. The NMI-watchdog engages only in case of a clock failure and can either generate an interrupt or a device reset.
