DRAM Access
10.4.1
DRAM Direct Connection
When address space A31–A24 = H'01 has been accessed, the corresponding space becomes a 16-
Mbyte DRAM space, and the DRAM interface function can be used to directly connect the
SH7040 Series to DRAM.
Row address and column address are always multiplexed for DRAM space. The amount of row
address multiplexing can be selected as from 9 to 12 bits by setting the AMX1 and AMX0 bits of
the DCR.
