Type Description
I/O
PCI/De-multiplexed Mode select
DPCI(1:0) = 00
DPCI(1:0) = 01
DPCI(1:0) = 10
DPCI(1:0) = 11
Pins DPCI(1:0) should be connected to V
achieve the appropriate mode selection.
DEMUX Address Bus
These pins provide the address bus for the De-
multiplexed Interface, when DPCI(1:0) = 10
Note:
Pin 124 ’A27’ provides a buffered PCI clock output
signal if configured in PCI operation mode
(DPCI(1:0) = ’00’).
Write/Read
This signal distinguishes write and read operations in
the De-multiplexed mode. It is tristate when the
MUNICH128X is in PCI mode.
A Pull-Up resistor to V
multiplexed mode is not used.
