7.7.1.3.2. Temperature Sensor 2(CPUTIN) SMI# Interrupt
The SMI# pin has two interrupt modes with CPUTIN.
(1) Comparator Interrupt Mode
T
(2) Two-Times Interrupt Mode
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
(Over Temperature) and continues to create interrupts until the temperature falls below T
This 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.
This mode is enabled by setting Bank0 Index 4Ch, bit 6, to zero.
In this mode, the SMI# pin can create an interrupt when the current temperature rises above T
or when the current temperature falls below T
however, and generates an interrupt, this mode does not generate additional interrupts, even if
the temperature remains above T
