FUNCTION

0V to +5V amplitude fan tachometer input.

Alternate Function: Fan on-off control output.

These multifunctional pins can be programmable input or

output.

Fan speed control. Use the Pulse Width Modulation (PWM)

technical knowledge to control the Fan's RPM.

Beep function for hardware monitor. This pin is low after

system reset.
