System for DMA data reception capable of confirming the content of a received data even if the received data is less than a preset length
 There are provided a reception apparatus using direct memory access (DMA), a reception method and a memory medium, allowing one to confirm the content of the received data in the DMA data reception, even when the received data are shorter than a preset data length. In a DMA reception apparatus capable of making a request for an interruption to the MPU 1 in response to the reception of data of y bytes from the host computer, there is also made a setting of x bytes in addition to the setting of y bytes, in order to confirm the data content when the length of the data transmitted from the host computer is less than y bytes, and a request for interruption is made upon reception of data of x bytes from the host computer.
