   4          Description of Software: 
   5          	This program demonstrates the PLL functions:
   6          	<A HREF="/~ehartman/842/pll/Pll842Dly.html">PllDly()</A>, 
   7          	<A HREF="/~ehartman/842/pll/Pll842Wcd.html">PllWcd()</A> and 
   8          	<A HREF="/~ehartman/842/pll/Pll842Rcd.html">PllRdd()</A>.
   9          
  10          The test waits 1s to ensure PLL is stable, reads the CD bits and
  11          then checks the CD bits. If an error occurs P3.4 pulses every second.
  12          Then 0ms, 1ms, 255ms, 256ms, 257ms, 32.6s,33s and 65.535s are measured off with 
  13          P3.3 toggling after each time period. The periods can thus be checked on an 
  14          oscilloscope. If the test has passed P3.4 flickers continuously.
  15          Development progress: <A HREF="/~ehartman/814/pll/Pll814Df.html">Pll814.df</A>
