(3) One-Time Interrupt Mode
7.7.1.3.2
The SMI# pin has two interrupt modes with CPUTIN.
(1) Comparator Interrupt Mode
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
Once the temperature rises above T
generate additional interrupts, even if the temperature remains above T
falls below T
subsequent events do not generate interrupts. This is illustrated in the following figure.
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.
