I came across this article a while back but hadn't had a chance to play with it.
http://www.msp430launchpad.com/2010/08/using-usi-as-uart.html
Armed with a Sparkfun FTDI FT232R breakout board, linux, msp430-gcc and an msp430g2452
I put the code below on it and was able to use putty connected @ 2000000 bps to send
data to my linux box. The bit duration is a blazing 500ns wow!
Hmm .. interesting
