Yes... However, check out the footnotes on pages 20-22... There are
actually several levels of register 'masking' going on.  I don't think
this is my poblem, though, since I can't change LCR at all.  I think
this means one of two things:

1.) I'm sending incorrect signals to the device
2.) Reding LCR return 0x00, so therefore the general registers are
inaccesible, including LCR.

I suspect (1), since I haven't been able to change any registers yet,
and a hard reset does not result in register reads returning the
defaults that are specified int he datasheet.

I'll poke around with debug, and tell you what I find; off the list
unless people are interested in using this thing later on.
