I don't see the names "TRxB" or "TRCxB" in my documentation, so I think we're
talking about the same pin here (Transmit/Receive Clock, subscript B).

We'd be interested to know whether you/InSync have determined conclusively
that TRxCb is being correctly configured as an input (and staying that way).

(I'd tell you exactly which bit I'm talking about in which register, but I
don't see it at the moment...I'll ask Chris again tomorrow.)
