Each IOE drives a row, column, MegaLAB, or local interconnect when
used as an input or bidirectional pin. A row IOE can drive a local,
MegaLAB, row, and column interconnect; a column IOE can drive the
column interconnect.

Any LE can drive a
pin through the row,
column, and MegaLAB
interconnect.
Row Interconnect
LAB
An LE can drive a pin through the
local interconnect for faster
clock-to-output times.
Figure 27
shows how a row IOE connects to the
MegaLAB Interconnect

interconnect. Each IOE data
and OE signal is driven by
the local interconnect.
