Appendix B : Watchdog Timer Setting
B.1 Watchdog Timer Working Procedure
Watchdog Timer (WDT) is a special hardware device that monitors the computer
system during normal operation. WDT has a clock circuit that times down from a
set number to zero. If a monitored item occurs before the timer reaches zero, WDT
resets and counts down again. If for some reason the monitored item doesn’t
occur before the timer reaches zero, WDT performs an action, such as a diagnos-
tic operation (rebooting the computer).
You must enter timer values into WDT Configuration Register (Write the control
value to the Configuration Port), and clear WDT counter (read the Configuration
Port).
