9.5.10
Figure 9.43 shows an example of a connection between the LSI and the burst MPX device.
Figures 9.44 to 9.47 show the burst MPX space access timings.
Area 6 can be specified as the burst address/data multiplex I/O (MPX-I/O) interface using the
TYPE2 to TYPE0 bits in the CS6BCR register. This MPX-I/O interface enables the LSI to be
easily connected to an external memory controller chip that uses an address/data multiplexed 32-
bit single bus. In this case, the address and the access size for the MPX-I/O interface are output to
D25 to D0 and D31 to D29, respectively, in address cycles. For the access sizes of D31 to D29,
see the description of the CS6WCR register. Address pins A25 to A0 are used to output normal
addresses.
In the burst MPX-I/O interface, the bus size is fixed at 32 bits. The BSZ1 and BSZ0 bits in
CS6BCR must be specified as 32 bits.
In the burst MPX-I/O interface, a software wait and hardware wait using the WAIT pin can be
inserted. In read cycles, a wait cycle is inserted automatically following the address output even if
the software wait insertion is specified as 0.
