Abstract
PURPOSE: To decrease the number of the input/output terminal as well as to facilitate easy alteration of the machine numbers by taking the machine numbers into the control circuit while the system is being cleared for the system in which the machine number of the LSI-formed input/output control circuit is set outside the control circuit.
CONSTITUTION: The data process system comprises CPU10, LSI-formed input/ output control circuit 11 and input/output apparatus 12 which is controlled by circuit 11. In such process system, machine number setting circuit 13 is connected to circuit 11. Then register 22 to take the data of bus line 111 into control circuit 11, comparator circuit 21 to compare the output of register 22 with the output of data line 102 and address FF23 are installed respectively. And the machne number set through setting circuit 13 is taken into circuit 11 while system clear signal SCLR is delivered from CPU1.
