Abstract
A PC card wherein a voltage supplied by an auxiliary battery is confirmable from an external device in a state in which an interface is maintained. A selection signal from an address decode circuit changes to a significant condition when a given address in an unused memory area is accessed in accordance with an address signal, with the result that a MOSFET transistor turns on so that the auxiliary battery makes contact with a voltage detector to detect the voltage of the auxiliary battery. The detection result is temporarily stored in a register and output as a portion of data to the external device at the time that a register output enable signal changes to a significant condition by an output enable signal.
