DESCRIPTION
OVT_MD.
There are two OVT# signal output type.
0_BIN : Comparator Mode: (Default)
Temperature exceeding Tcritical (Critical Temperature) causes the OVT# output
activated until the temperature is less than T_HYST (Critical Temperature Hysteresis).
1_BIN : Interrupt Mode:
7
Setting temperature exceeding Tcritical (Critical Temperature) causes the OVT# output
activated indefinitely until reset reading temperature sensor TD1/TD2/TD3/TD4/TR1/TR2
registers.
Temperature exceeding Tcritical (Critical Temperature), then OVT# reset, and then
temperature going below T_HYST (Critical Temperature Hysteresis) will also cause the OVT#
activated indefinitely until reset by reading temperature sensor
TD1/TD2/TD3/TD4/TR1/TR2(reading interrupt status). Once the OVT# will not be activated
by exceeding Tcritical (Critical Temperature), then reset, if the temperature remains above
T_HYST (Critical Temperature Hysteresis), the OVT# will not be activated again.
EN_OVTR2.
6
Enable temperature sensor TR2 over-temperature (OVT) output if set to 1. Default 0;
disable OVTR2 output through pin OVT#. The pin OVT# is wire OR with OVTD1, OVTD2,
OVTD3, OVTD4 and OVTR1.
EN_OVTR1.
5
Enable temperature sensor TR1 over-temperature (OVT) output if set to 1. Default 0;
disable OVTR1 output through pin OVT#. The pin OVT# is wire OR with OVTD1, OVTD2,
OVTD3, OVTD4 and OVTR2.
EN_OVTD4.
4
Enable temperature sensor TD4 over-temperature (OVT) output if set to 1. Default 0;
disable OVTD4 output through pin OVT#. The pin OVT# is wire OR with OVTD1, OVTD2,
OVTD3, OVTR1 and OVTR2
EN_OVTD3.
3
Enable temperature sensor TD3 over-temperature (OVT) output if set to 1. Default 0;
disable OVTD3 output through pin OVT#. The pin OVT# is wire OR with OVTD1, OVTD2,
OVTD4, OVTR1 and OVTR2
EN_OVTD2.
2
Enable temperature sensor TD2 over-temperature (OVT) output if set to 1. Default 0;
disable OVTD2 output through pin OVT#. The pin OVT# is wire OR with OVTD1, OVTD3,
OVTD4, OVTR1 and OVTR2
EN_OVTD1.
1
Enable temperature sensor TD1 over-temperature (OVT) output if set to 1. Default 0;
disable OVTD1 output through pin OVT#. The pin OVT# is wire OR with OVTD2, OVTD3,
OVTD4, OVTR1 and OVTR2
OVTPOL.
0
Write 1, OVT# active high. Write 0, OVT# active low.
