Serial ATA

Hardware monitoring

A built-in, proactive hardware monitoring system in the Super I/O
monitors the CPU temperature, CPU fan speed, and voltage levels
to prevent overheating and/or component damage, effect timely
failure detection, and ensure stable supply of current for critical
components.

Watchdog Timer

The watchdog timer (WDT) monitors system operations based on
user-defined configurations. The WDT can be programmed for dif-
ferent time-out periods, such as from 1 to 255 seconds or from 1 to
255 minutes. The WDT generates a reset signal, then a reset
request, after failure to strobe it within the programmed time
period. A register bit may be enabled to indicate if the watchdog
timer caused the reset event. The WDT register is cleared during
the power-on sequence to enable the operating system to take
appropriate action when the watchdog generates a reboot.
