ABSTRACT:
A microcomputer that reduces through current of output buffers, and thus, reduces power line fluctuation that occurs when a large number of the bus lines connected to output buffers change state at the same time. The through current (or punch-through current) is reduced through the use of a detector circuit that detects the number of bus lines which are changing state and a decoder circuit that changes the impedance of output buffers, which drive the bus lines to external components, when the number of bus lines changing state at a given time exceeds a predetermined number.
