MICROPROCESSOR AND METHOD OF OPERATING MICROPROCESSOR

摘要

PROBLEM TO BE SOLVED: To reduce the power consumption of a microprocessor, and to enhance the function of the microprocessor.

SOLUTION: This data processor has a plurality of sub-circuits 36 and 38, and a clock pulse generating circuit 84 for generating a clock signal therein. A detecting circuit detects the assertion of a control signal, and a disable circuit disables the clock signal to one or more of the sub-circuits 36 and 38 in response to the control signal. A circuit for separating one or more of the sub-circuits selectively from an accessory input and output pin to impart compatibility with a desirable microprocessor architecture by separating the pin.
