Abstract

See full text

A PC card includes a circuit having a first function, a circuit having a second function, a selector for selecting either the first or second function, and a slot-type identification mechanism for identifying the type of PC card slot. The selector selects either the first or second function according to an identification signal received from the slot-type identification mechanism. Upon insertion into a PC card slot, the PC card self-identifies an operation mode.
