For the CAN module, you must look at the SJA1000 datasheet to get all 
the details, especially about bit timing. The LPC2129 CAN module is an 
SJA1000 on the ARM bus. The datasheet is at:

http://www.semiconductors.philips.com/acrobat/datasheets/SJA1000_3.pdf

Also, see CANBTR.py at:
http://groups.yahoo.com/group/lpc2000/files/Tools/

It's a tool I have programmed in Python (http://www.python.org) to 
calculate the best CANBTR value for a particular bitrate. Just change 
the constants at the beginning of the file to your values and it should 
give accurate results. It has been tested several times with the 
LPC2129.
