// FILE: Example_2833xAdc.c
//
// TITLE: DSP2833x ADC Example Program.
//
// ASSUMPTIONS:
//
// This program requires the DSP2833x header files.
//
// Make sure the CPU clock speed is properly defined in
// DSP2833x_Examples.h before compiling this example.
//
// Connect signals to be converted to A2 and A3.
//
// As supplied, this project is configured for "boot to SARAM"
// operation. The 2833x Boot Mode table is shown below.
// For information on configuring the boot mode of an eZdsp,
// please refer to the documentation included with the eZdsp,

// DESCRIPTION:
//
// This example sets up the PLL in x10/2 mode.
//
// For 150 MHz devices (default)
// divides SYSCLKOUT by six to reach a 25.0Mhz HSPCLK
// (assuming a 30Mhz XCLKIN).
//
// For 100 MHz devices:
// divides SYSCLKOUT by four to reach a 25.0Mhz HSPCLK
// (assuming a 20Mhz XCLKIN).
//
// Interrupts are enabled and the ePWM1 is setup to generate a periodic
// ADC SOC on SEQ1. Two channels are converted, ADCINA3 and ADCINA2.
//
// Watch Variables:
//
// Voltage1[10] Last 10 ADCRESULT0 values
// Voltage2[10] Last 10 ADCRESULT1 values
// ConversionCount Current result number 0-9
// LoopCount Idle loop counter
