SPDIF de-emphasis

Does the SPDIF receiver in the ADAU1442/1445/1146 detect !EMPH and apply appropriate filtering?  Neither the datasheet or the SigmaDSP help file remarks on this and there's no emphasis flag on SigmaStudio SpdifIn's block which could be used to toggle a de-emphasis filter (at least in SigmaStudio 3.1; haven't checked 3.2 or 3.3).  So I'm guessing either the parts don't support de-emphasis or it's automatically handled.  It would be helpful to know which.
