Temperature sensors 2 and 3 Over-Temperature (nOVT)
Temperature sensors 2 and 3 Over-Temparature (nOVT) have two modes of operation.
They are
programmed at Bank1 and Bank2 CR[52h] bit1 . These two bits needs to be programmed to the same
value.
(1) Comparator Mode :
Temperatures exceeding TO cause the nOVT output to go active until the temperature is less than
THYST. (Figure 17)
(2) Interrupt Mode:
Temperatures exceeding TO causes the nOVT output to go active indefinitely until reset by reading
temperature sensor 2 or sensor 3 registers. If the temperature exceeds TO, and then nOVT is reset,
and then the temperature going below THYST causes the nOVT to go active until reset by reading
temperature sensor2 or sensor 3 registers. Once the nOVT is activated by exceeding TO, then reset, if
the temperature remains above THYST, the nOVT is not be activated again. (Figure 17).
