Abstract
To provide a microcomputer provided with an input/output circuit which does not become an output state to a slave microcomputer until an output signal from a read-only memory is terminated by providing a delay means for a switching control part which changes over the input/output circuit. Even if switching control for changing over the input/output circuit 5 from a data input state from the read-only memory to the output state to the other microcomputer is executed, the delay means 2 delays the change-over of the input/output circuit 5 until the output signal from the raed- only memory is terminated. Namely, a master microcomputer does not output a signal to a data bus during delay generated by using D.FF and an NOR gate even if the transfer of the signal with the slave microcomputer is to be executed even after the output signal is outputted to the data bus by the read- only memory. Thus, the output signal of the read-only memory is prevented from colliding with the output signal of the master microcomputer.
