5.7 OVT# interrupt mode
The OVT# mode selection bits are at Bank0 Index18h bit4, Bank1 Index52h bit1 and Bank2 Index52h
bit1.
(1) Comparator Mode :
Temperature exceeding T_O causes the OVT# output activated until the temperature is less than T_HYST.
( Figure 5-19)
(2) Interrupt Mode:
Temperature exceeding T_O causes the OVT# output activated indefinitely until reset by reading
temperature sensor registers. Temperature exceeding T_O, then OVT# reset, and then temperature
going below T_HYST will also cause the OVT# activated indefinitely until reset by reading temperature
sensor registers. Once the OVT# is activated by exceeding T_O , then reset, if the temperature remains
above T_HYST , the OVT# will not be activated again.( Figure 5-19)
