An electronic device, information processing device, and adapter device enabling smooth internal circuit switching and other operations are provided. In the electronic device 200, the serial interface 21 and parallel interface 22 are connected via a data bus 23 to the register 24 and data buffer 25, and this data buffer 25 is connected to an ECC circuit 26. The register 24, data buffer 25 and ECC circuit 26 are connected to the memory 28 via a memory interface and sequencer circuit 27. The register 24 is connected to the controller 29, and data input and output is controller. The interfaces 21 and 22 are switched by means of control signals from this controller 29. That is, switching between these interfaces 21 and 22 is performed through discrimination, by the controller 29, of a portion of the data written to the register 24.
