//  MSP-FET430P430 Demo - ADC12, Single Conversion on Channel A14
//
//  This example shows how to perform a single ADC12 conversion on a single
//  channel. It uses AVcc for the reference and performs a single conversion on
//  channel A14. The conversion results are stored in ADC12MEM0. Test by
//  applying a voltage to channel A14, then setting and running to a break point
//  at the "_NOP()" instruction. To view the conversion results, open a
//  register window with the debugger and view the contents of ADC12MEM0.
//  ACLK = n/a, MCLK = SMCLK = default DCO, ADC12CLK = ADC12OSC
//
