PURPOSE:To shorten the data transfer time, by providing an address counter which uses address information, which is outputted to a date terminal from a processor, as the initial value and is counted up each time when the processor outputs a prescribed address to an address terminal. CONSTITUTION:When data of the first word is stored in a start address DA1 of a transfer destination region, address counters ADC-L and ADC-H are counted up by one, and their contents are set to an address DA2. Next, a processor CPU adds 1 to an address SA1 stored in an index register X to make an address SA2 and compares the last address SAN stored in a region END with the address DA2 stored in the index register X; and if they do not coincide with each other, the processor CPU executes the transfer of data TD2 of the second word from a step S18 by an instruction BNES18 in a step S22. |
