ABSTRACT:
A direct memory access controller has a data assembly function by means of a single temporary register. This single register used for a number of channels replaces temporary registers which have been necessary for the respective channels to carry out channel transition during data assembly. By controlling channel transition during data assembly, it is possible to carry out DMA transfers in which channel transition is made during data assembly, thereby preventing an increase in the chip size.
