Interface between HD64180, HD64645 and HD64646
Note: In 80 family MPUs, I/O space is separate from memory space in software. Thus the LCTC,
a part of I/O, needs the ORed signals of the interface signals and IOE. So IOE and RD,
and IOE and WR should be ORed to satisfy tAS, the timing of CS, RD, and WR.
