ADC INITIALIZATION CODE EXAMPLE
/* Ensure the correct sampling time has elapsed before
/* Configure ADC port
/* Configure sample clock source and Conversion Trigger mode.
/* Configure ADC voltage reference
/* Configure ADC conversion clock */
/* Configure input channels,
/* No inputs are scanned.
/*Clear ADC conversion interrupt*/
/* Enable ADC conversion interrupt*/
/* Turn on the ADC module */
/* Start sampling the input */
/* End Sampling and start Conversion*/
/* The DONE bit is set by hardware when the convert sequence
/* The ADIF bit will be set. */
Unsigned Fractional format, Manual conversion trigger,
Manual start of sampling, Simultaneous sampling,
No operation in IDLE mode.
