Comparator Interrupt Mode
Two-Time Interrupt
Mode
(2) Two-Time Interrupt Mode
This mode is enabled by setting T
HYST
(Temperature Hysteresis) lower than T
O
and setting Bank0
Index 4Ch, bit 5 to zero.
In this mode, the SMI# pin can create an interrupt when the current temperature rises above T
O
or
when the current temperature falls below T
HYST
. Once the temperature rises above T
O
, however,
and generates an interrupt, this mode does not generate additional interrupts, even if the
temperature remains above T
O
, until the temperature falls below T
HYST
. This interrupt must be reset
by reading all the interrupt status registers, or subsequent events do not generate interrupts. This
is illustrated in the figure above.
(3) One-Time Interrupt Mode
This mode is enabled by setting T
HYST
(Temperature Hysteresis) lower than T
O
and setting Bank0
Index 4Ch, bit 5 to one.
In this mode, the SMI# pin can create an interrupt when the current temperature rises above T
O
.
Once the temperature rises above T
O
, however, and generates an interrupt, this mode does not
generate additional interrupts, even if the temperature remains above T
O
, until the temperature
falls below T
HYST
. This interrupt must be reset by reading all the interrupt status registers, or
subsequent events do not generate interrupts. This is illustrated in the following figure.
