The W83627HF OVT# signal is only related to temperature sensor 2 and 3(VTIN2 / VTIN3). They
have two modes:
(1)Comparator Mode:
(2)Interrupt Mode:
Setting Bank1/2 CR[52h] bit 2 to 0 will set OVT# signal to comparator mode. Temperature ex-
ceeding TO causes the OVT# output activated until the temperature is less than THYST.(See
Figure 8.12)
Setting Bank1/2 CR[52h] bit 2 to 1 will set OVT# signal to interrupt mode. Setting Temperature
exceeding TO causes the OVT# output activated indefinitely until reset by reading temperature
sensor 2 or sensor 3 registers. Temperature exceeding TO , then OVT# reset, and then tempera-
ture going below THYST will also cause the OVT# activated indefinitely until reset by reading
temperature sensor2 or sensor 3 registers. Once the OVT# is activated by exceeding TO, then
reset, if the temperature remains above THYST, the OVT# will not be activated again.(See Fig-
ure 8.12)
