* Description:
*  This is source code for the datasheet example of the Quadrature Decoder 
*  Component.
*
*  Quadrature Decoder Component is driven by two PWM's. Each 500 counts which 
*  are totaled by the Quadrature Decoder Component on Character LCD add one 
*  line of the Vertical Bargraph. When 4000 counts are counted - the Control 
*  Register generates the index signal and Quadrature Decoder is Reset. Number
*  of counts resets to zero, and the procedure cyclically repeats.
