6.5.1 W83783S temperature sensor 2 SMI# interrupt has two modes:
(1) Comparator Interrupt Mode
Setting the T
Comparator Interrupt Mode. Temperature exceeds T
and this interrupt will be reset by reading all the Interrupt Status Register. Once an interrupt event has
occurred by exceeding T
again when the next conversion has completed. If an interrupt event has occurred by exceeding T
and not reset, the interrupts will not occur again. The interrupts will continue to occur in this manner
until the temperature goes below T
(2) Two-Times Interrupt Mode
Setting the T
Temperature exceeding T
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 T
