Row-to-IOE Connections
When an IOE is used as an input signal, it can drive two separate row
channels. The signal is accessible by all LEs within that row. When an IOE
is used as an output, the signal is driven by a multiplexer that selects a
signal from the row channels. Up to eight IOEs connect to each side of
