PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of improving accuracy of A/D conversion processing.SOLUTION: An electronic apparatus 200 comprises: a main control unit (main CPU 210) that performs processing for a plurality of pieces of digital data and outputs a control signal in accordance with the processing for the plurality of pieces of digital data; and sub control units (sub CPUs 220A, 220B) that start A/D conversion processing for an analog signal input from the outside in accordance with a timing instructed by the control signal and, after the completion of the A/D conversion processing, transfer digital data generated by the A/D conversion processing through a communication line 230 connected to the main control unit (main CPU 210) to the main control unit (main CPU 210). The sub control units (sub CPUs 220A, 220B) perform the A/D conversion processing when communication signals (SCL, SDA) are not generated on the communication line.SELECTED DRAWING: Figure 2 |
