Abstract
PURPOSE: To omit the data correction with every input by having the interruption due to the transfer end data tag bit in place of the normal software when the input/ output order of the keyboard is through.
CONSTITUTION: The data is transferred to main memory 1 from keyboard 4 through display buffer 2 to be displayed on CRT3. In this case, the transfer end data tag bit is added to memory 1, and the fuction is provided to the data buffer to turn on the transfer end data tag bit when the data transfer to memory 1 is completed. Thus, the interruption is given by the transfer end data tag bit in place of the normal sofware interruption when the input/output order of keyboard 4 is over and with the input of the data from keyboard 4 to the data with which the transfer end data tag bit is on. As a result, no consideration is required for the data correction at every input.
