Column-to-IOE Connections
When an IOE is used as an input, it can drive up to two separate column
channels. When an IOE is used as an output, the signal is driven by a
multiplexer that selects a signal from the column channels. Two IOEs
connect to each side of the column channels. Each IOE can be driven by
column channels via a multiplexer. The set of column channels is different
for each IOE (see Figure 17).
