Abstract
An I/O signaling circuit having a single path through the circuit which can be configured to operate in one of a plurality of modes. A first circuit in the I/O signaling circuit adjusts the current flowing from a power supply to ground. A second circuit adjusts the voltage between a high potential terminal and low potential potential terminal through a remote secondary processing device. A processor determines the proper mode in which the circuit is to operate and then generates signals to adjust the first and second circuits to configure the circuit.
