A one indicates VIN3 exceeds the high or low limit. A zero indicates VIN3 is
in the safe region.
A one indicates VIN2 exceeds the high or low limit. A zero indicates VIN2 is
in the safe region.
A one indicates VIN1 exceeds the high or low limit. A zero indicates VIN1 is
in the safe region.
A one indicates VCC exceeds the high or low limit. A zero indicates VCC is in
the safe region.
Enable temperature 1 OVT fault trigger SMI resister.
Enable temperature 0 (local temperature) OVT fault trigger SMI resister.
Return one when read.
Enable temperature 2 OVT fault trigger SMI resister.
Enable Voltage 3 fault trigger SMI resister.
Enable Voltage 2 fault trigger SMI resister.
Enable Voltage 1 fault trigger SMI resister.
Enable Voltage VCC fault trigger SMI resister.
A one indicates VT1 temperature sensor has exceeded high limit or
below the hysteresis limit. Write 1 to clear this bit, write 0 will be ignored.
A one indicates VT0 temperature sensor (local temperature) has
exceeded the high limit or below the hysteresis limit. Write 1 to clear this
bit, write 0 will be ignored.
Return 0 when read.
A one indicates VT2 temperature sensor has exceeded high limit or
below the hysteresis limit. Write 1 to clear this bit, write 0 will be ignored.
A one indicates VIN3 has exceeded the high or low limit continuously for
the times set by V_FAULT_QUEUE register. Write 1 to clear this bit,
write 0 will be ignored.
