Description
Anode Connection to Second Thermal Diode.
Cathode Connection to First Thermal Diode.
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 k? typical pull-up.
Also functions as the output from the XOR tree in XOR test mode.
