PROBLEM TO BE SOLVED: To provide a communication circuit, physical value measuring apparatus, electronic apparatus, mobile apparatus, communication method or the like, capable of notifying a master device of an error on a command signal by performing data communication based on a master-slave type communication protocol.SOLUTION: A communication circuit (interface part 10) includes: an input part (input shift register 11) to be inputted a data signal; an output part (output shift register 29) for outputting a response signal if a data signal is inputted; and a command determination part 14 for determining properness of a command signal included in a data signal. The output part outputs a negative acknowledge response signal as a response signal if a command signal is determined as improper by the properness determination. |
