Clause 46 - Preamble
Shimon raised a comment against D2.0 SC 188.8.131.52 (#252) asking for the
removal of the requirement that the preamble be a fixed length on
receive; this was accepted in principle. However, I seem to remember in
the discussion on this comment at Irvine that there was agreement that
the Start control code and SFD couldn't appear in the same RXD column;
there would be one or more clock edges between the Start code and SFD.
The new text (in D2.1 SC 184.108.40.206) does not explicitly rule in or out
the appearance of the SFD in the same column as the Start code; this is
consistent with Shimon's original suggested remedy.
Is this something that has slipped through the rewrite or has False
Memory Syndrome struck again?
