Description
Anode Connection to First Thermal Diode.
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).
Analog Input. Monitors +5 V power supply.
Alternatively, this pin can be reconfigured as a bidirectional THERM pin. Can be used to time and monitor assertions
on the THERM input. For example, it can be connected to the PROCHOT output of an Intel Pentium 4 processor or to
the output of a trip point temperature sensor. This pin can also be used as an output to signal overtemperature
conditions.
Analog Input. Monitors +12 V power supply.
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).
Supports VRM10 solutions.
Analog Input. Monitors +2.5 V supply, typically a chipset voltage.
Analog Input. Monitors processor core voltage (0 V to 3 V).
Digital Output (Open Drain). Pulse width modulated output to control Fan 1 speed. Requires 10 kΩ typical pull-up.
Also functions as the output from the XOR tree in XOR test mode.
