  • Synchronous serial transfer apparatus and synchronous serial transfer method
    Patent number: 5970096
    Abstract: In a synchronous serial transfer apparatus, the number of lines which are necessary for a serial transfer is reduced, and even when a master/slave operation is to be performed, a serial transfer is possible between any communication apparatuses without using communication apparatuses which have different structures from each other such as a master and slave apparatuses and without using a master apparatus. Communication apparatuses (TR1 to TR3) are connected parallel to each other by one communication line (TRL). A potential fixing apparatus (VC), which fixes a potential on the communication line (TRL) to "High" or "Low" when outputs from all communication apparatuses (TR1 to TR3) are in a "High-Z" state, is connected to the communication line (TRL).
