PURPOSE:To prevent missing of a data by informing generation of an error to a sender side when a reception error takes place at the time of transferring data in the serial data transfer of 2-wire type start-stop synchronism type, and allowing the sender side receiving the information to transfer the data having an error again. CONSTITUTION:The processor consists of a switching means 1, a data retransfer command means 2 and a data retransfer means 3. When an error takes place during the transfer of a serial data, the switching means 1 switches a reception enable signal into a reception disable signal, the data retransfer command means 2 issues the retransmission command of a serial data to the sender side equipment and the sender side equipment receives the command and transfers the serial data again to the receiver side. Thus, missing of data at serial data transfer is prevented. |
