Temperature exceeding T
temperature sensor registers. Temperature exceeding T
temperature going below T
reading temperature sensor registers. Once the OVT# is activated by exceeding T
the temperature remains above T
The HM_SMI#/OVT# pin (pin 5) is a multi-function pin. The function is selected at Configuration
Register CR[29h] bit 6. The OVT# mode selection bits are at Bank0 Index18h bit4, Bank1 Index
52h bit1 and Bank2 Index 52h bit1.
