Description
System Management Bus bidirectional clock line.
System Management Bus bidirectional data line.
System Management Bus Alert – active low input can
be used to generate an SMI# (System Management
Interrupt) or to wake the system.
Description
General purpose input / output pins. Upon a
hardware reset, these pins should be configured as
inputs.
As inputs, these pins should be able to generate an
interrupt to the Module host.
