All input signals to the IOE can be inverted at the IOE.
The tri-state buffer is active low. The DDIO megafunction represents the tri-state buffer as active-high with an
inverter at the OE register data port. Similarly, the aclr and apreset signals are also active-high at the input ports
of the DDIO megafunction.
The optional PCI clamp is only available on column I/O pins.
