In transition to the boot mode and transition from the boot mode to another mode,
mode switching via RES input is necessary.
During this switching period (period during which a low level is input to the RES pin),
the state of the address dual port and bus control output signals (AS,RD,WR) changes.
Therefore, do not use these pins as output signals during this switching period.
When making a transition from the boot mode to another mode, the mode programming
