ARM Cortex-A8 based AM335x processors from Texas Instruments include a dedicated hardware watchdog timer (WDT) module that can be used to monitor system behavior and reset the system if a fault condition is detected. The WDT module uses a timer circuit to periodically generate a pulse that must be acknowledged by software in order to prevent a system reset. If the software fails to acknowledge the pulse within a specified time period, the WDT module will assume that the software is no longer functioning correctly and will initiate a system reset. This helps ensure the system remains stable and responsive even in the event of unexpected faults or errors.
