// MSP430FR59xx Demo - ADC12B, Using an External Reference
//
// Description: This example shows how to use an external positive reference for
// the ADC12B. The external reference is applied to the VeREF+ pin. AVss is used
// for the negative reference. A single conversion is performed on channel A0.
// The conversion results are stored in ADC12BMEM0 and Test by applying a voltage
// to channel A0, then setting and running to a break point at the "_NOP()"
// instruction. To view the conversion results, open an SFR window in debugger
// and view the contents of ADC12BMEM0.
// NOTE: VeREF+ range: 1.4V (min) to AVCC (max)
// VeREF- range: 0V (min) to 1.2V (max)
// Differential ref voltage range: 1.4V(min) to AVCC(max)
// (see datasheet for device specific information)
