I referenced errors regarding this equation when I posted my fractional
divider utility a good while back.  There are also some errors in the %error
listing in example table.

The output of correct equation doesn't produce valid results for baud rates
greater than 38400 with PCLK of 3 MHz.  Silicon?  It's not much of a concern
for the LPC214x since core needs to run at minimum 18MHz, but may be an
issue on the LPC2101/2/3.

For those who are not aware my fractional divider utility enumerates every
DLM/DLL/MULVAL/DIVADDVAL register combination to come up with register list
sorted by lowest %error.
