//******************************************************************************

// MSP-FET430P120 Demo - ADC10, DTC Sample A0 64x, ××cc, Repeat Single, DCO

//

// Description: Use DTC to sample A0 64 times with reference to ××cc. Software

// writes to ADC10SC to trigger sample burst. In Mainloop MSP430 waits in LPM0

// to s××e power until ADC10 conversion burst complete, ADC10_ISR(DTC) will

// force exit from any LPMx in Mainloop on reti. ADC10 internal oscillator

// times sample period (16x) and conversion (13x). DTC transfers conversion

// code to RAM 200h - 280h. P1.0 set at start of conversion burst, reset on

// completion.

// //* MSP430F1232 or MSP430F1132 Device Required *//
