Please refer to “Application Example: De-multiplexed Bus Interface” on page 407
for an de-multiplexed bus application example.
mode it is the responsibility of the glue logic to meet the bus timing/protocol of the
PCI specification and of the memory devices that are used in the system. When
the DSCC4 operates in master mode, the bus cycle, for example, can be delayed
by the TRDY signal.
