ABSTRACT:
A microprocessor having three kinds of bus cycle mode including a read cycle, a write cycle and an instruction fetch cycle, comprises a register having three bits corresponding to the read cycle, the write cycle and the instruction fetch cycle, respectively. A combinational circuit is connected to receive a code set in the register and coded information indicating the kind of bus cycle mode. An output circuit receiving an output of the combinational circuit operates to output the output of the combinational circuit in synchronism with a start of a corresponding bus cycle.
