7.7.1.3.2. Temperature Sensor 2(CPUTIN) And Sensor 3(AUXTIN) SMI# Interrupt
The SMI# pin has two interrupt modes with CPUTIN / AUXTIN.
(1) Comparator Interrupt Mode
T
HYST
SMI#
T
This mode is enabled by setting Bank0 Index 4Ch, bit 6, to one.
In this mode, the SMI# pin can create an interrupt when the current temperature exceeds T
Temperature) and continues to create interrupts until the temperature falls below T
interrupt can be reset by reading all the interrupt status registers, or subsequent events do not
generate interrupts. This is illustrated in the figure below.
