PROBLEM TO BE SOLVED: To simplify the configuration of an electronic apparatus in the electronic apparatus that switches an operation mode between a mode in which a data read destination of an internal memory consisting of a volatile memory is an external memory consisting of a nonvolatile memory, and a mode in which a data read destination of the internal memory is an external device.SOLUTION: The electronic apparatus switches between a master mode and a slave mode according to a logical value of a mode storage area. The electronic apparatus is configured to select the master mode in a power activation when the mode storage area of the internal memory is in an initial state. Consequently, mode data including the logical value are read from the external memory by the internal memory. This configuration can dispense with switches and terminals for switching the respective modes to simplify the apparatus while suppressing the number of components of the apparatus. |
