4.1 Watchdog Timer implementation

The Watchdog Timer used in this Embedded Computer is the POST Watchdog Timer. The Watchdog Timer circuit is in SuperIO and can be controlled by the BIOS setup menu through the system BIOS for different boot phases.

Please refer to the table below for more details on the implementation of the Watchdog Timer.

Watchdog Timer Implementation Default Timeout
POST Watchdog Timer	This Watchdog Timer is for recovering the system from crashes during BIOS takeover to OS.	The timeout value is determined by the BIOS settings.
	NOTE: The default setting for the BIOS item is set to enabled.
*OS Watchdog Timer	No implementation. User needs to write software in OS to keep updating the watchdog timer to prevent it from timing out. The application is executed on payload.	N/A
