This application note explains interfacing the PDIUSBD12 to Hitachi H8S/2357.

The bus controller partitions the total 16Mbytes address space into eight areas, 0 to 7, in 2Mbytes units. The bus controller will output CS0 to CS7 when external address space for each area is accessed. PDIUSBD12 can be mapped to any address area, where is simple for interfacing requirements. In above example circuit, PDISUBD12's base address is mapped to H'FFFF08 in CS7 area. Assuming that it is the only external device within this area, CS7 can be directly connected to CS_N.
