The part features a monitor mode which is optimised to operate with
either a 4.1952MHz crystal clock source (or multiples of 4.1952MHz) or
a 4MHz crystal (or multiples of 4MHz). This supports designs which use
the MSCAN module, which is generally clocked from a 4MHz, 8MHz or
16MHz crystal. The table below outlines the available baud rates for a
range of crystals and how they can match to a PC baud rate.
Care should be taken when setting the baud rate since incorrect
baud rate setting can result in communications failure.
