6.6.3 The W83637HF temperature sensor 1(SYSTIN) SMI# interrupt has two modes
Setting the T
are two kinds of interrupt modes, which are selected by Index 4Ch bit5:
(1) Comparator Interrupt Mode
(2) Two-Times Interrupt Mode
(3) One-Time Interrupt Mode
Setting the T
the Comparator Interrupt Mode. Temperature exceeds T
interrupt and this interrupt will be reset by reading all the Interrupt Status Register. Once an
interrupt event has occurred by exceeding T

Temperature exceeding T

Register. Once an interrupt event has occurred by exceeding T

Temperature exceeding T
