Advanced I/O Controller with Motherboard GLUE Logic
Datasheet
The pin has an internal pull-down resistor that selects the non-SMSC mode. To select this mode, the
pin should be left unconnected. This configuration clears the LD_NUM bit to ‘0’ and the associated
functionality corresponds to the existing functionality in the part when the LD_NUM bit=0.
Connecting this pin to VTR will select the SMSC mode of the logical device numbering. This
configuration sets the LD_NUM bit to ‘1’ and the associated functionality corresponds to the existing
functionality in the part when the LD_NUM bit=1.
