3.5 Watchdog Timer (WDT) Function
The working algorithm of the Watchdog Timer (WDT) function can be described as a counting process. The Time-
Out Interval can be set through software programming. The availability of the time-out interval settings by software or
hardware varies from board to board.
The built-in Mini-ITX board allows users to control the WDT through dynamic software programming. The WDT starts
counting when it is activated. It sends out a signal to system reset or to non-maskable interrupt (NMI) when the time-out
interval ends. To prevent the time-out interval from running out, a re-trigger signal will need to be sent before the counting
reaches its end. This action will restart the counting process. A well-written WDT program should keep the counting
process running under normal conditions. The WDT should never generate a system reset or NMI signal unless the
system encounters problems.
