2.6 OVT# interrupt mode
The OVT# signal is only related with temperature sensor 2 and 3 (VTIN2 / VTIN3).
(1) Comparator Mode :
(2) Interrupt Mode:
2.6.1 The W83627HF temperature sensor 2 and 3 Over-Temperature (OVT#) has
the following modes
Setting Bank1/2 CR[52h] bit 2 to 0 will set OVT# signal to comparator mode. Temperature

Setting Bank1/2 CR[52h] bit 2 to 1 will set OVT# signal to interrupt mode. Setting Temperature
exceeding T

temperature remains above T
