摘要：It provided a synchronization time division multiplexing bus communication method using serial communication interface, in which input and output data lines of a host and several slaves being connected with the bus. Then the detailed communication mode was stated. The method could be applied in all MCU, meanwhile meets the requirements of high speed for the real time performance, and solves the problem of bus communication between internal modules of a device and realizes controllable communication real time performance, reduced hardware circuit complexity as well as enhanced universality and reliability.
