Abstract: A data transfer system includes a slave device, and a host device that is connected to the slave device via at least a power supply line, a clock line, a command line, and a data line. A CMD line is continuously driven to a low level in a period from when the supply of at least a first clock is stopped to when the second clock is supplied (period form timing t5 to timing t6).

Abstract: A slave device is to be connected to a host device through at least one of a first interface and a second interface. The slave device includes a first terminal group used for the first interface, a second terminal group used for the second interface and a signal input and output part. The first terminal group and the second terminal group are provided at positions identical to terminal groups of another slave device to be connected through a third interface different from the second interface. The signal input and output part supplies a signal to a predetermined terminal in the first terminal group within a predetermined period from supply of power to the slave device, the signal notifying the host device whether the second terminal group is compliant with the second interface.
