Address Multiplexing: When area 2 or area 3 is designated as DRAM space, address
multiplexing is always performed in accesses to DRAM. This enables DRAM, which requires row
and column address multiplexing, to be connected to this LSI without using an external address
multiplexer circuit. Any of the five multiplexing methods shown below can be selected, by setting
bits AMXEXT and AMX2–0 in MCR for area 2 or 3 DRAM. The relationship between the
AMXEXT and AMX2–0 bits and address multiplexing is shown in table 13.15. The address
output pins subject to address multiplexing are A17 to A1. The address signals output by pins A25
to A18 are undefined.
