4 Watchdog
The C6B-SLH board has a watchdog function implemented by an
embedded controller.
The watchdog can be enabled and configured in the BIOS Setup.
If the watchdog is enabled a counter is started which generates a reset
if it is not retriggered within a programmable time window.
Possible watchdog delays: 1s, 5s, 10s, 30s, 1min, 5min, 10min, 30min
Possible watchdog timeout: 0.4s, 1s, 5s, 10s, 30s, 1min, 5min, 10min
The time delay starts as soon as it is enabled in the BIOS.
MSC provides a software API which gives the application software
access to the Watchdog functionality if needed.
