What you described looks very similar to the UART equation.  CAN is
much more complex than that.  First you need the baud rate prescaler
to get the can clock, then you need to define SJW (syn jump width),
then TSEG1 and TSEG2 to get the correct baud rate (see pg 197 in um).
 I've tired using some to values that Xanalyser gave me, but none of
them seem to work.  It was much easier to get it to work on the atmel
8051 can uc.
