When the selected interface is the only active interface, all function blocks in the memory card may be reset. If interfaces other than the selected interface are active, only the selected interface may be reset. ## Claims ### Claim 1 A method of resetting a memory card having a plurality of interfaces and a plurality of function blocks, each function block being associated with a corresponding interface, the method comprising: detecting a reset signal for a selected interface of the plurality of interfaces;
