A processing method and apparatus for utilizing a single serial communication line in a versatile manner

摘要

All existing communications are used for connection to other systems using a single serial communication line. However, in this case, for example, CPU _B transfers the operation result to the data reception processing to receive a command from the CPU to the CPU _AA.;However, this case is not available for data for a command to the operation result between the CPU _A and CPU _B will effect a significant effect on the operation between the two systems (CPU _A, CPU _B).;Thus, the present invention provides an algorithm that utilizes a single serial communication line in a versatile manner, so that it does not affect the operation between the two systems (CPU _A and CPU _B ) and receives a small amount of data, such as a debug message of the CPU _A , To be monitored.
