subsequent events do not generate interrupts. If the interrupt is reset, the SMI# pin continues to
create interrupts until the temperature goes below T
This mode is enabled by setting T
Index 4Ch, bit 5 to zero.
This mode is enabled by setting T
Index 4Ch, bit 5 to one.
In this mode, the SMI# pin can create an interrupt when the current temperature rises above T

falls below T
subsequent events do not generate interrupts. This is illustrated in the following figure.
