Abstract

PURPOSE: To prevent the circuit constitution from being complicated even for increment of the number of kinds of interrupt, by constituting the signal transfer circuit to the program counter with an OR gate circuit and an AND gate circuit.
CONSTITUTION: It is supposed that program routines to be executed when interrupt signals are applied to interruption signal input terminals 6, 7 and 8 are stored in, for example, addresses 800W81F, addresses 820W83F, and addresses 840W85F respectively in program ROM3. First, start address 800 is set to register 30, and next, disabled signal input terminal 23 is set to "L". Aftrr that, when the interrupt input signal is given to terminal 6, the code at address 800 is set to program counter 1, and the CPU executes the program at address following address 800. When the control reaches the 1ast addresses 81F, the CPU stops. At addresses 800W81F, the instruction is included which can accept the nect interruptinon siganl input. Next, when the interruption signal is applied to terminals 7 and 8, the similar operations are executed.
