ATTRIBUTE
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
temperature
exceeding T
going below T
indefinitely until reset by reading temperature sensor
1/2/3(reading interrupt status). Once the OVT# will not be
activated by exceeding T
remains above T
again.
<10> - ACPI Mode:
always send an OVT# pulse signal (22us, if not a
suddenly temperature jump)when the temperature over
the ACPI temperature increment value defined at Index
5Eh.
Enable temperature sensor 3 over-temperature (OVT)
output if set to 1. Default 0, disable OVT2 output through
pin OVT#. The pin OVT# is wire OR with OVT1 and
OVT2.
Enable temperature sensor 2 over-temperature (OVT)
output if set to 1. Default 0, disable OVT2 output through
pin OVT#. The pin OVT# is wire OR with OVT1 and
OVT3.
Enable temperature sensor 1 over-temperature (OVT)
output .if set to 1. Default 0, disable OVT1 output through
pin OVT#. The pin OVT# is wire OR with OVT2 and
OVT3.
Over-Temperature Polarity. Write 0, OVT# active high.
Write 1, OVT# active low. Default is 1 .
Temperature exceeding T
Setting temperature exceeding T
If set to 1 then enable ACPI OVT# output. Which is
