6.4.2 Voltage
SMI# interrupt for voltage is shown as figure 5-14. Voltage exceeding or going below high limit will cause an interrupt if the
previous interrupt has been reset by writing “1” all the interrupt Status Register. Voltage exceeding or going below low limit will
result in the same condition as voltage exceeding or going below high limit.
6.4.3
SMI# interrupt for fan is shown as figure 5-15 . SMI# will be asserted when the fan speed count exceeds or goes below the fan
limit (Value RAM 2Ch~2Dh, 2Eh~2Fh).
6.5 VOLT_FAULT# (Voltage Fault Signal)
When voltage leaps from the security range setting by BIOS, the warning signal VOLT_FAULT# will be activated. Shown in figure
