MAX 9000 Programmable Logic Device Family Data Sheet
A row interconnect channel can be fed by the output of the macrocell
through a 4-to-1 multiplexer that the macrocell shares with three column
channels. If the multiplexer is used for a macrocell-to-row connection, the
three column signals can access another row channel via an additional
3-to-1 multiplexer. Within any LAB, the multiplexers provide all
48 column channels with access to 32 row channels.
Row-to-I/O Cell Connections
Figure 8
illustrates the connections between row interconnect channels
and IOCs. An input signal from an IOC can drive two separate row
channels. When an IOC is used as an output, the signal is driven by a
10-to-1 multiplexer that selects the row channels. Each end of the row
channel feeds up to eight IOCs on the periphery of the device.

Column-to-I/O Cell Connections
Each end of a column channel has up to 10 IOCs (see
Figure 9
). An input
signal from an IOC can drive two separate column channels. When an
IOC is used as an output, the signal is driven by a 17-to-1 multiplexer that
selects the column channels.
