7.7
The SMI#/OVT# pin is a multi-function pin. The function is selected at Configuration Register CR[29h]
bit 6.
7.7.1
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 7.12)
7.7.2
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 7.13)
