Abstract

PURPOSE:To improve the processing capability, by providing the first and the second buffers in the interface part to perform the operation, where start information such as a command is stored in the first buffer, and the operation, where data transfer and end information are stored in the second buffer, independently of each other. CONSTITUTION:A common control part 1, a line control part 2, and a interface control part 3 are provided to constitute a communication control device which performs a series of operations of start, data transfer, and end for a CPU6 by this control part 3. This interface control part 3 is provided with the first buffer 8 where start information such as a command is stored when the start from the CPU6 is detected and the second buffer 9 where data transfer information and end information from the common control part 1 are stored. The operation, where start information is stored in the buffer 8, and the operation, where transfer information and end information are stored in the buffer 9, are performed independently of each other by transfer control circuits provided in respective buffers 8 and 9, thereby improving the processing capability.
