Abstract
A signal supplying unit includes a plurality of terminals, a plurality of signal sources, each of the plurality of signal sources outputting a signal, a detecting circuit for detecting whether or not at least the one of the plurality of terminals is coupled to a terminal of an external unit, and a selecting circuit for selecting signals to be supplied to the plurality of terminals from signals output from the plurality of signal sources in accordance with a detecting result obtained by the detecting circuit. In addition, a signal supplying unit includes a first terminal, a second terminal, a first signal source for outputting a first signal, a second signal source for outputting a second signal, a third signal source for outputting a third signal, a detecting circuit for detecting whether or not the first terminal is coupled to a terminal of an external unit and for outputting a detecting signal, and a selecting circuit for selectively supplying either the second signal output from the second signal source or the third signal output from the third signal source to the second terminal in accordance with the detecting signal output from the detecting circuit.
