6.5.2 The W83783S temperature sensor 1 SMI# interrupt has three modes
(1) Comparator Interrupt Mode
(2) Two-Times Interrupt Mode
(3) One-Time Interrupt Mode
Temperature exceeding T
Interrupt Status Register. Once an interrupt event has occurred by exceeding T
the temperature remains above the T
has 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
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
remains above the T
Temperature exceeding T
