UART0 and UART1 baud rate calculations

2006-02-23 by dodge1955

Has anyone ever done some type of spreadsheet on the different UxDLL
and UxDLM values along with MULVAL and DIVVAL for the most popular
crystals to make the baud rate come out perfect (like 9600, 19200,
etc).  The manual has the examples for 20Mhz, but it would be nice to
have some appendix that has a table of values that come out even for a
variety of commonly used crystals.  11.059Mhz is obviously an easy
one, but others like 12Mhz, 15Mhz, etc. are not as easy and I know
some crystals may not have a perfect value and thus have an error factor.
