Abstract
A microcomputer includes: a central processing unit (CPU); a data transfer apparatus (DTC); and a storage apparatus (RAM). The data transfer apparatus includes a plurality of register files each including a mode register storing the transfer mode information, an address register to which the address information is transferred, and a status register (SR) representing information that specifies the transfer information set. The data transfer apparatus checks the information of the status register, to determine whether to use the transfer information set held in the register files or to read the transfer information set from the storage apparatus and to rewrite a prescribed one of the register files. The data transfer apparatus performs data transfer based on the transfer information set stored in one of the register files.
