Most systems need to be self reliant If an error should occur it is typically not possible to wait for the system to be rebooted manually In some cases such as apace probes the system is simply disabled In other cases the speed at which a human operator would reset the system would be too slow to meet the uptime requirements of the product A watchdog timer is a piece of hardware that can be used to automatically detect system anomalies and reset the processor if the case any problems are found Generally speaking a watchdog timer is based on a counter that counts down from an initial value to zero The software selects the counter s initial value and periodically restarts it Should the counter reach zero before the software restarts it the software is presumed to be malfunctioning and the processor s reset signal is asserted Thus the processor will be restarted as if a human operator had cycled the power Watch Dog Sample code Copyright c 2008 Lanner Electronic Inc rights reserved Watchdog control utility for LEB 7900 include lt stdio h gt include lt string h gt include lt dos h gt include lt stdlib h gt include lt inlines pc h gt define INDEX PORT 0 2 define DATA PORT Ox2f defineCR20_REG Ox20 This register indicate the device s ID define W83627UHG ID OxA2 void help printf Lanner Electronics Inc 2009 05 22 n printf Watchdog timer control V1 0 for LEB 7900 n n printf wdb
