Note: If S/PDIF Out sources the S/PDIF Tx 1 Widget and OutEnable=0,
the S/PDIF signal is still transmitted, but the payload of the S/PDIF signal
is filled with zeros. In this way, the OutEnable register acts as a S/PDIF
Mute. When sourcing the S/PDIF TX 1 Widget, the user can have the
S/PDIF Out pin drive 0 by setting DigEn (in the S/PDIF TX 1 Widget) to 0.
Note: If S/PDIF Out sources the S/PDIF In widget and OutEnable=0, the
S/PDIF Out pin drives zero. The Digen register has no context in this
configuration, and is ignored.
