I've seen issues running at 12MHz as well.  If PLL multiplier is greater
than 1, I have no problems regardless of pclk rate.  If multiplier is 1, or
if the PLL is not enabled, there is not communications.  I've checked 115200
at all possible pclk frequencies, and only had issue with 12MHz.  Perhaps
the equation needs modification to take into account fundamental frequency?
