If I set "Reverse serial" on an Arria 10 transceiver using TTK, what mode, Pre-CDR or Post-CDR, is set?

Hi Chee,

I finally got to doing this. I dumped the registers after setting Reverse Loopback and the pattern of bit values don't look like either pre or post CDR. So, I tried setting the bits according to the tables that you mention using tcl. When I set the "pre" values via tcl, TTK reports that it is "Metallic" loopback.
