OVT# Mode Select. There are three OVT# signal output
type.
<00> - Comparator Mode: (Default)
activated until the temperature is less than T
<01> - Interrupt Mode:
output activated indefinitely until reset reading temperature
sensor 1/2/3 registers. Temperature exceeding T
OVT# reset, and then temperature going below T
also cause the OVT# activated indifinitely until reset by
reading temperature sensor 1/2/3. Onece the OVT# will not
be activated by exceeding T
temperature remains above T
actived agian.
<10> - ACPI Mode:
always send an OVT# signal when the temperature over
the ACPI temperature increment value defined at Index
4Fh.
Enable CPUT2 temperature sensor over-temperature
(OVT) output if set to 1. Default 0, disable CPUT2 OVT
output through pin OVT#. The pin OVT# is wire OR with
OVT1 and OVT2.
Enable CPUT1 temperature sensor
(OVT) output if set to 1. Default 0, disable CPUT1 OVT
output through pin OVT#. The pin OVT# is wire OR with
OVT1 and OVT3.
Enable internal temperature sensor over-temperature
(OVT) output if set to 1. Default 0, disable OVT1 output
through pin OVT#. The pin OVT# is wire OR with OVT2
register to non-zero value, the OVT# signal will be
actived at pointer of
DIFFREG (i.e. DIFFREG*n, where n is non-zero
integer). The default value is 5 degree C.
