DESCRIPTION
The input of temperature sensor 1. It is used for system
temperature sensing.
The output of over temperature Shutdown. This pin indicates
the temperature is over the temperature limit. (Default after
LRESET#)
System Management Interrupt channel output.
VID input detection, also with output control.
0 to +3 V amplitude fan tachometer input.
Receive data from serial flash. This pin is connected to SO of
serial flash..
0 to +3 V amplitude fan tachometer input.
