A circuit has a programmable mode control section, and a receiver section with first and second input terminals and an output terminal. The method and apparatus involve setting the mode control section to one of first and second states in response to user input, and operating the receiver section in first and second operational mode when the mode control section respectively has the first and second states, wherein in the first operational mode the receiver section provides higher performance and consumes more power than in the second operational mode.
