ABSTRACT:
A read/write configuration (44) is provided for switching signals between a source (46) and either a single output (60) or a plurality of outputs (60) and (62). A control circuit (68) operates to control a signal switching circuit (64) and a power supply switching circuit (66) in response to a control signal input thereto. More particularly, in a reading mode, the switches within signal switching circuit (64) are opened while the switch within power supply switching circuit (66) is closed. Further, in a writing mode, the switches within signal switching circuit (64) are closed while the switch within power supply switching circuit (66) is opened.
