6.6.2 Voltage
SMI# interrupt for voltage is Two-Times Interrupt Mode. Voltage exceeding high limit or going below
low limit will causes an interrupt if the previous interrupt has been reset by reading all the interrupt
Status Register. (Figure 20-1)
6.6.3 Fan
SMI# interrupt for fan is Two-Times Interrupt Mode. Fan count exceeding the limit, or exceeding and
then going below the limit (set at value ram index 3Bh and 3Ch) , will causes an interrupt if the
previous interrupt has been reset by reading all the interrupt Status Register. (Figure 20-2)
