5.6.4
The W83627THF temperature sensor 2(CPUTIN) and sensor 3(AUXTIN) SMI#
interrupt has two modes and it is programmed at CR[4Ch] bit 6.
(1) Comparator Interrupt Mode
Temperature exceeding T
causes an interrupt and this interrupt will be reset by reading all the
O
Interrupt Status Register. Once an interrupt event has occurred by exceeding T
, then reset, if the
O
temperature remains above the T
, the interrupt will occur again when the next conversion has
HYST
completed. If an interrupt event has occurred by exceeding T
and not reset, the interrupts will not
O
occur again. The interrupts will continue to occur in this manner until the temperature goes below
T
. ( Figure 5-17 )
HYST
(2) Two-Times Interrupt Mode
Temperature exceeding T
causes an interrupt and then temperature going below T
will also
O
HYST
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
, then reset, if the temperature remains above
O
the T
, the interrupt will not occur. (Figure 5-18 )
