msp430g2231 - use external square wave from ATTiny @ 12 MHZ as LFXT1 clock

	//***********************************************************
	// runfast.c - Using 12MHZ external square wave clock as LFXTCLK
	// source MCLK/SMCLK from 12MHZ wave and blink led
	// at 60Hz
	//
	// Use an external clock ( I'm using an attiny running at 12.00 MHZ
	// with the CLKOUT fuse enabled ) as the MCLK/SMCLK for the MSP430.
	// I've been told you could also use an external oscillator like an
	// ECS-100A-160. I ordered some of these to verify.

	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
