An integrated circuit (20) configures the active level of an input, output, or input/output pin by sensing a logic state on the pin's bonding pad (21) at the inactivation of a reset signal, such as a power-on reset signal. The integrated circuit (20) selects a true or complement signal to provide to or from an internal circuit (25). The voltage level on the pin is latched on the active-to-inactive transition of the power-on reset signal. Thus, the use of proper board-level termination resistors (70, 71) programs the pins to the desired active logic level without the need for additional logic circuitry or a dedicated device pin.
