  • Patent number: 10942885
    Abstract: This disclosure relates to a communicating apparatus, a communication method, a program, and a communication system that each enable execution of more reliable communication. A communicating apparatus includes a transmitting and receiving part that executes transmission and reception of signals with at least one or more other communicating apparatuses through a data signal line and a clock signal line, and an error avoiding part that, in a state where a communication system configured to be able to execute communication through a bus already operates, executes a process of avoiding occurrence of any error occurring when a communicating apparatus is additionally connected to the communication system. This technique is applicable to, for example, a bus IF.
