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