8.7.1.3.2. Temperature Sensor 2 (CPUTIN) And Sensor 3 (AUXTIN) SMI# Interrupt
The SMI# pin has three interrupt modes with CPUTIN / AUXTIN.
(1) Shut-down Interrupt Mode
In this mode, the SMI# pin can create an interrupt when the current temperature rises above T
or Shut-down mode high limit temperature, and when the current temperature falls below T
Shut-down mode low limit temperature. Once the temperature rises above T
generates an interrupt, this mode does not generate additional interrupts, even if the temperature
remains above T
all the interrupt status registers, or subsequent events do not generate interrupts, except the first
time current temperature rises above Shut-down mode high limit temperature. This is illustrated in
the following figure.
This mode is enabled by setting Bank0 Index 4Ch, bit 6 to zero and Bank0 Index 40h, bit 6-5 to
one.
