Function
PCI Mode (DEMUX connected to VSS):
LBI Data
(GMODE.PERCFG=0XX
These pins provide the 16 bit Data bus for the
Local Bus Interface.
LBI Address/Data
(GMODE.PERCFG=100
These pins provide the 16 bit multiplexed
Address/Data bus for the Local Bus Interface.
Demultiplexed Mode (DEMUX connected
to VDD3) :
DEMUX Address Bus (31:16)
These pins provide the 16 most significant
address lines for the de-multiplexed interface.
LBI Hold Request
LHOLD = ’1’ is used for normal bus drive
mode.
LHOLD = ’0’ requests LBI to enter hold mode.
A Pull-Up resistor to V
if LBI is not used.
LBI Bus Request
The DSCC4 asserts LBREQ = ’0’ to request
the local bus and deasserts the signal
LBREQ = ’1’ after regaining bus.
