Abstract
PURPOSE: To simplify the constitution as well as to ensure a high-speed information exchange by securing the data transmission in such form as the access of the memory via the control signal line and the data signal line.
CONSTITUTION: Data processor 1 of the microcomputer and the like is connected to analog or digital input/output circuits 2-1W2-n via downward control signal line A, downward data line B, upward control signal line C and upward data D each. In case processor 1 writes the data into circuit 2, the sending of the WRITE address proper to the input/output circuit to dats line B is started and at the same time signal line A is turned to "1" with the data sending start continued to circuit 2. After this, processor 1 sends out the data, and circuit 2 takes in the subsequent data in case the WRITE address belongs to its own. When processor 1 reads the data out of circuit 2, the READ address proper to the input/output circuit is sent to data line B and at the same time signal line A is turned to "1". And circuit 2 starts to send the data to data line D and also turns signal line C to "1" if the READ address belongs to its own.
