DEMUX I PCI/De-multiplexed Mode Select

DEMUX = 0 indicates normal PCI operation.

DEMUX = 1 indicates that the MUNICH32X is

operated in De-multiplexed mode.

W/R I/O Write/Read

This signal distinguishes write and read

operations in the De-multiplexed mode. It is

tristate when the MUNICH32X is in PCI mode.

A Pull-Up resistor to VDD3 is recommended if

De-multiplexed mode is not used.
