The W83627HF temperature sensor 1 SMI# interrupt has two modes
°1±Comparator Interrupt Mode
°2±Two-Times Interrupt Mode
Setting the T
to the Comparator Interrupt Mode. Temperature exceeds T
an interrupt and this interrupt will be reset by reading all the Interrupt Status Register. Once an in-
terrupt event has occurred by exceeding T
T
has occurred by exceeding T
will continue to occur in this manner until the temperature goes below T
Setting the THYST lower than TO will set temperature sensor 1 SMI# to the Two-Times Interrupt
Mode. Temperature exceeding TO causes an interrupt and then temperature going below THYST
will also cause an interrupt if the previous interrupt has been reset by reading all the interrupt
Status Register. Once an interrupt event has occurred by exceeding TO, then reset, if the tem-
perature remains above the THYST, the interrupt will not occur. °See Figure 8.9±
