Abstract
PURPOSE: To enhance the function of the 1-chip information processor by using the external connection terminal (selection terminal) which was used for designation of the register as other control terminal.
CONSTITUTION: When the data which is identical to the data held in address register 13 is transmitted from address bus AB, comparator 14 detects the coincidence signal to make AND gates 15 and 16 active. In this case, if writing signal WR is supplied, the signal WR is supplied to register 12 from gate 16 via signal line 18. And the data sent from other information processor through data bus DB is written. While in case reading signal RD is supplied, the signal RD is supplied to gate circuit 17 via signal line 19 from the output end of gate 15. Thus the data held in register 12 is sent to other information processor via data bus DB.
