摘要：
In a high level function complex system comprising a combination of a plurality of microcomputer application instruments, a data transmission system of each microcomputer application instrument includes a reservation status holder for setting and holding a communication reservation condition in response to a communication reservation request generated in one of the microcomputer application instruments. The reservation status holder also generates a communication reservation signal. The data transmission system further includes a statlis discriminator to detect whether a communication bus is in a communication start possible condition, and if so detected, to generate a communication start enable signal. A communication start instruction generator generates a communication start signal to instruct a communication start in response to the communication reservation signal and the communication start enable signal.
