Section 6 Bus Controller (BSC)
(d) Address/data multiplexed I/O interface
The number of access cycles in data cycle of the address/data multiplexed I/O interface is the
same as that in the basic bus interface. The number of access cycles in address cycle can be
specified as two or three cycles by the ADDEX bit in MPXCR.
Table 6.6 lists the number of access cycles for each interface.
Table 6.6
(4)
The assert and negate timings of the strobe signals can be modified as well as number of access
cycles.
• Read strobe (RD) in the basic bus interface
• Chip select assertion period extension cycles in the basic bus interface
• Data transfer acknowledge (DACK3 to DACK0) output for DMAC single address transfers
