Abstract

PURPOSE:To shorten a waiting time of a priority frame signal in case a non- priority frame signal which is being transmitted is long, and to transmit quickly a priority frame by constituting a titled device so that a non-priority frame which is being sent out is halted and a priority frame signal is sent out, in case the priority frame signal is generated when the non-priority frame signal is being sent out, and the remainder of said halted non-priority frame is sent out after ending sending-out of the priority frame signal. CONSTITUTION:As for a non-priority frame U1, first of all, following a start flag SF, header information H is sent out, and subsequently, a data D is sent out. When a priority frame signal P2 is inputted to the second transmitting buffer 5, status information PS of a status register 6 is set, a control circuit 7 checks a length of an unsent part of a non-priority frame signal which is being sent out at present, and in case it is longer than a value Lu determined in advance, sending-out of the non-priority frame signal is halted, and the priority frame signal P2 is set to a shift register 8 and sent out.
