   4          Description of Software: 
   5          	This program demonstrates the <A HREF="/mcc/softw/842/adc/Adc842D.html">SAR ADC</A> functions. 
   6          	; <A HREF="/mcc/softw/842/adc/Adc842Cfg.html">AdcCfg()</A>, <A HREF="/mcc/softw/842/adc/Adc842Go.html">Ad
             -cGo()</A>,
   7          	; <A HREF="/mcc/softw/842/adc/Adc842Bsy.html">AdcBsy()</A>, <A HREF="/mcc/softw/842/adc/Adc842Rd.html">Ad
             -cRd()</A>
   8          	; <A HREF="/mcc/softw/842/adc/Adc842Cal.html">AdcCal()</A> and <A HREF="/mcc/softw/842/adc/Adc842Get.html
             -">AdcGet()</A>.
   9          	Software communicates with a terminal at 9600 baud. Program shows 
  10          	help screen with a command list. Then continuous conversions are 
  11          	started and displayed. While measurements are output the user can 
  12          	issue single key commands to change settings. 
  13          	Also included are a help and wait option.
