Keyboard Clock.
Keyboard Data.
PS2 Mouse Clock.
PS2 Mouse Data.
Beep function for hardware monitor. This pin is low after
system reset.
General-purpose I/O port 2 bit 1.
CASE OPEN Detection. An active-low input from an external
device when the case is open. This signal can be latched if pin
VBAT is connected to the battery, even if the W83627UHG is
turned off.
Pull up a 2-MΩ resistor to VBAT is recommended if useless.

Reference Voltage (2.048 V)
Temperature sensor 2 input. It is used for CPU temperature
sensing.
Temperature sensor 1 input. It is used for system temperature
sensing.
Over temperature Shutdown Output. This pin indicates the
temperature is over the temperature limit. (Default after
LRESET#)
System Management Interrupt channel output.
0 to +5 V amplitude fan tachometer input.
DC/PWM fan output control.
CPUFANOUT and SYSFANOUT are default PWM mode.
Power LED output. This pin is tri-stated as default.
