Abstract
A one-chip microcomputer including a central processing unit, a direct memory access controller and a random-access memory. In a DMA operation mode, data stored in the random-access memory is transmitted through common terminals to the exterior by means of a time-division control circuit or registers for parallel-serial conversion. The common terminals are also used for a CPU operation mode.
