A method and apparatus for providing computer code updates through an integrated circuit card (smart card) interface. The smart card interface within a computer control device determines whether the card that is inserted into the smart card interface is either a memory card or a conventional smart card. Once the smart card interface has detected that the memory card has been inserted, the interface requests data from the card. The interface provides the computer code to the memory of the computer controlled device to update the computer code therein.

A method and apparatus for implementing an interface for ISO/7816 and NRSS cards with a single connector. The apparatus is a computer controlled device comprising a card reader further comprising an interface controller and a connector. The connector forms the interface between the card reader and the IC card. The interface controller determines whether the IC card inserted into the card reader is an ISO/7816 or NRSS card. Additionally, the interface controller implements the correct interface for the detected IC card. The method comprises the steps of determining whether a IC card is an ISO/7816 or NRSS card and implementing an interface for the identified IC card.

Method and apparatus for supporting two different types of integrated circuit cards with a single connector

In an electronic circuit and/or component, such as a television, that requires a tri-state condition when the electronic circuit/component is powered up, a tri-state circuit may be employed. The present tri-state circuit includes a control circuit operably coupled to an enable input of a tri-state buffer. During power-up of the electronic circuit, the control circuitry is operable to prevent data from passing from an input of the tri-state buffer to an output of the tri-state buffer until a predetermined time period wherein the control circuitry is operable to allow data to pass from the input to the output of the tri-state buffer.
