| 1. An input/output device to be used by an electronic device, comprising:
an interface having a plurality of pins that include data pins, a command pin, and a power signal pin, the interface being
connectable to the electronic device;
a register file pre-storing operation mode information of the input/output device, the operation mode information indicating
one of first and second operation modes;
a transmitter configured to transmit the operation mode information stored in the register file to the electronic device via
one of the plurality of pins, when a first command that requests reading of the operation mode information is received from
the electronic device via the command pin; and
a data transfer unit configured to execute data transfer between the input/output device and the electronic device, the data
transfer unit transferring data using the data pins to which signal assignment was performed by the electronic device according
to the operation mode information, wherein:
the data transfer unit uses all of the data pins for data transfer in the first operation mode;
the data transfer unit uses one of the data pins for data transfer in the second operation mode;
the register file stores operation voltage information indicating an operation voltage of the input/output device; and
the transmitter transmits the operation voltage information stored in the register file to the electronic device via the command
pin, when a second command that requests reading of the operation voltage information is received from the electronic device
via the command pin.
