// MSP-FET430P430 Demo - ADC12, Single Conversion on Channel A12
//
// 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 A12. The conversion results are stored in ADC12MEM0. Test by
// applying a voltage to channel A12, 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
