成するようにして構成される。The option frame transmission method of the present invention is provided in a data transmitting/receiving device that performs data communication according to an arbitrary communication protocol in accordance with an instruction from a higher-level processor, in which the upper-level processor sends first data to the data transmitting/receiving device according to the communication protocol. comprising a transmission instruction and a second data transmission instruction that does not depend on a communication protocol, and while the data transmission/reception device is performing data transmission/reception processing according to the first data transmission instruction and in accordance with the communication protocol; The second data transmission instruction intentionally generates an error frame or a state mismatch frame, thereby creating a mismatch in the communication protocol or an error state between communication mates.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

を送出する。Normally, in data transmission according to the communication protocol, the upper processor v10 stores transmission data in advance in the common memory 12 using the external bus 13, and instructs the data transmission/reception device 11 to send a numbered frame transmission instruction 14, The communication protocol control unit 111 of the data transmitting/receiving device 11 takes out the data stored in the shared memory 12 using the internal bus 112, packetizes it according to the communication protocol, and sends the data to the line 1.

1 inputs the received data using the internal data bus,
The communication protocol control unit 111 disassembles and analyzes the bug according to the communication protocol, and if it is normal, the internal data bus 112
is used to store the data in the shared memory 12 and notify the upper processor 10 of the data reception report 16. At that time, if the result of disassembling and analyzing the bucket is abnormal, error processing is performed.
