Description
Monitors 5 V Supply Using Internal Resistor Dividers.
Monitors 12 V Supply Using Internal Resistor Dividers.
Monitors 2.5 V Supply Using Internal Resistor Dividers.
Alternatively, this pin can be reconfigured as a bidirectional THERM pin. Can be
connected to PROCHOT output of processor to time and monitor PROCHOT assertions.
Can be used as an output to signal overtemperature conditions or for clock modulation
purposes.
Monitors CPU VCC Voltage (to maximum of 3.0 V). All voltage inputs can have their
resistor dividers removed allowing for full-scale input of 2.25 V of ADC channel.
Pulse Width Modulated Output to Control FAN 1 Speed. Open drain requires 10 kΩ
typical pull-up.
Also functions as the output for the XNOR tree test enable mode.
