Abstract
A data communication control system includes first and second control units each having a microcomputer, the second control unit carrying out a first interrupt processing which starts in accordance with a first timing signal having a first period, and a second interrupt processing which starts in accordance with a second timing signal having a second period, the second interrupt processing being for the second control unit to receive data transferred from the first control unit. The second timing signal is generated in the first control unit in such a manner that adjacent ones of the second timing signal have values of the second period different from each other. Therefore, even if the first interrupt processing and the second interrupt processing conincide with each other the coincidence is not continued whereby transfer of data can be reliably carried out.
