A method of controlling data sending and receiving operations between two microprocessors. A first controlled-side microprocessor receives an optional one of a data sending request signal and a data receiving request signal from a second controlling- side microprocessor. The first microprocessor also receives a select signal of a logic OR signal of both request signals, and determines if the optional one request signal indicates "receiving request" or "sending request" at the same time when it responds to the select signal, thereby executing the requested operation. Hence, even if the first microprocessor does not receive the select signal and the sending/receiving signal at a time, the first microprocessor can determine simulta- neously with the receipt of the select signal if it should send or receive the data, resulting in a higher-speed data processing.
