7.7.5
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 10-1.)
7.7.6
SMI# interrupt for fan is Two-Times Interrupt Mode. Fan count exceeding the limit, or exceeding and
then going below the limit, will causes an interrupt if the previous interrupt has been reset by reading
all the interrupt Status Register. (Figure 10-2.)

(1) Comparator Interrupt Mode
Temperature exceeding T
Interrupt Status Register. Once an interrupt event has occurred by exceeding T
temperature remains above the T
completed. If an interrupt event has occurred by exceeding T
will not occur again. The interrupts will continue to occur in this manner until the temperature goes
below T
Temperature exceeding T
