DESCRIPTION
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 over-temperature
(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
and OVT3.
Over-Temperature Polarity. Write 1, OVT# active high.
Write 0, OVT# active low. Default 0.

DESCRIPTION

Temperature SMI Mode Select.
<00> - Comparator Interrupt Mode:
Temperature 1/2/3 exceeds T_O (Over-temperature)
limit causes and interrupt and this interrupt will be
reset by reading all the Interrupt Stauts.
<01> - Two Time Interrupt Mode:(Default)
This bit use in temperature sensor 1/2/3 interrupt
mode with hysteresis type. Temperature exceeding
T_O, causes an interrupt and then temperature going
below T_HYST will also cause an interrupt if the previous
interrupt has been reset by reading all the interrupt
Status Register. Once an interrupt event has occurred
by exceeding T_O, then reset, if the temperature
remains above the T_HYST.
<10> - One Time Interrupt Mode:
This bit use in temperature sensor 1/2/3 interrupt
mode with hysteresis type. Temperature exceeding T_O
(Over-temperature, defined in Bank 1/2) causes an
interrupt and then temperature going below T_HYST
(Hysteresis temperature, defined in Bank 1/2) will not
cause an interrupt. Once an interrupt event has
occurred by exceeding T_O, then going below T_HYST,
and interrupt will not occur again until the temperature
exceeding T_O.
