Input fixed values for the MPMD0, MPMD1, and BSMODE pins. These values cannot be changed after power is
supplied. The values of pins MD0 to MD14, MD19 to MD24, MD27, MD28, MDT0 and MDT1 are input upon power-on
reset using the PRESET# pin. Power-on reset results in switching to a different function.
Note that this LSI does not have pins MD15 to MD18, MD25, and MD26.
Legend:
"0" means logic low level input, "1" means logic high level input.
"—" means either "0" or "1", but its level must be fixed.
