Section 6 Bus Controller (BSC)
Both extension state T
basic bus cycle, or only one of these, can be specified for individual areas. Insertion or non-
insertion can be specified for the T
register, and for the T
6.6
If areas 6 and 7 of the external address space are specified as address/data multiplexed I/O space
in this LSI, the address/data multiplexed I/O interfacing can be performed. In the address/data
multiplexed I/O interface, peripheral LSIs that require address/data multiplexing can be connected
directly to this LSI.
6.6.1
In the address/data multiplexed I/O interface, areas 6 and 7 are designated as the address/data
multiplexed I/O space by setting the MPXE bit in MPXCR to 1.
6.6.2
With the address/data multiplexed I/O space, the data bus and address bus are multiplexed. Table
6.4 shows the relation between the bus width and corresponding address output.
