Interface configuration for a memory card and memory card control device
Card detection pin and input pin configured to receive an interface reset signal are connected to each other in a high-speed data transfer memory card. A memory card control device noncompliant with the memory card initializes the interface reset signal to a memory card to a second electric potential, and then when the memory card control device detects a first electric potential of the card detection pin of the memory card, the memory card control device determines that the memory card is mounted. When the memory card is mounted in such a memory card control device, the memory card control device does not detect the mounting of the memory card, and thus does not start subsequent operation such as driving the interface reset signal to the first electric potential and supplying electric power to the memory card.
