摘要： An electronic card capable of changing communication functionality of a coupled electronic device is disclosed. A removable interface has at least a card detection pin which is set at a first state or a second state based on the coupled electronic device. A functional module provides a communication functionality via an access bus or a specific application bus based on whether the card detection pin is at the first state or the second state. A bridge is provided for bridging and converting signals of the interface bus on the removable interface into signals of the access bus or the specific application bus, or vice versa. A multiplexer device selects signals of the access bus or signals of the specific application bus based on whether the card detection pin is at the first state or the second state for being switched to the interface bus.
