Abstract
PURPOSE: To enable to increase the efficiency of the degree of circuit integration of input and output unit, by using a plurality of address signals accompanied with the program data as the various circuit and unit selection signals.
CONSTITUTION: The sequence control section 2' consists of the program counter 21', program memory section 22', operation section 23', and input and output selection section 24'. This selection 24' takes the address signal 23" in 8-bits accompanied with the program data 22" as the input signal and the 4-bits are output from the circuit selection signal line 5 as the circuit selection signals A0WA3 and connected to the gate circuit of each input and output unit. Further, the 3-bits A4WA6 of the signal 23" are converted into the input and output unit selection signal line in 8-bits at the decoder circuit 9 and output from this selection signal line. Further, the 1-bit A7 is fed to the input and output units 1W15 from the unit circuit selection signal line 7 as the unit circuit selection signals b0, b1 of positive and negative logic outputs, by the combination of the two NOT circuits 10.
