Abstract
PURPOSE: To ensure a highly efficient interface with a simple constitution of circuit, by detecting the operation of the latch deciding circuit in a latch circuit through the control circuit and then reading the data out of the latch circuit and then take it in.
CONSTITUTION: The latch circuit 2 is provided to give latching to data one by one, and each data signal is supplied to the FF5 serving as a control circuit via the input OR gate 4. The FF5 detects one of the signals to have a set working, and thus detects the operation of the data latch deciding circuit which is stored in the circuit 2 to read the data out of the circuit 2 and then take it in. Then the CPU6 resets the FF5 when the taking-in of the data is over. In such way, a highly effective interface is possible with a simple constitution of circuit.
