1. A data communication apparatus, comprising:
a transceiver coupled to a data path and configured to transmit or receive data through the data path; and
an interrupt circuit coupled to an interrupt path corresponding to the data path and configured to determine whether to allow any apparatus to occupy the data path, wherein the data path is structured to carry first data transmitted by the data communication apparatus and second data transmitted by another apparatus, and the interrupt path comprises a first line structured to carry a first interrupt signal transmitted by the data communication apparatus and a second interrupt signal transmitted by the other apparatus at different times, wherein the first line is coupled to a switching circuit comprising a plurality of transistors serially connected between a power supply terminal for providing voltages and the first line,
wherein the interrupt circuit generates the first interrupt signal for preventing the other apparatus from accessing the data path in response to an activation signal for transmitting or receiving the first data through the transceiver.
