register in common area. Moreover, in that case, a combination pin is set up and mapping is
simultaneously set up by the CS/WAIT controller. When CPU outputs logical address of the
local area, MMU outputs physical address to the outside address bus pin according to value
of bank setting-register. Access of external memory becomes possible therefore.
