    Abstract: PROBLEM TO BE SOLVED: To provide a new apparatus and method for input and output control reducing the time required for the input and output process of an on-chip memory unit via a JTAG port.
    SOLUTION: A signal indicating whether a memory unit is in a state where it is capable of the input and output process (ready state) or in a state where it is not capable of the input and output process (busy state) is received. When a display enters the ready state, instructions for performing the next input and output process of the memory unit (read, write data of such as programs, delete, verify, etc.) are issued so as to control the input and output process of the on-chip memory unit.
