6 General-Purpose Input/Output (GPIO) Interface
The GPIO interface consists of one GPIO port available via the MFUNC terminal by configuring the multifunction
configuration register (PCI offset E8h). GPIO powers up as a general-purpose input and is programmable via the
GPIO control register. Figure 6−1 shows the logic diagram for GPIO implementation.
