* 
* Description: These #defines are used in the PC_Disp???() functions.  The 'color' argument in these 
*              function MUST specify a 'foreground' color, a 'background' and whether the display will 
*              blink or not.  If you don't specify a background color, BLACK is assumed.  You would  
*              specify a color combination as follows: 
* 
*              PC_DispChar(0, 0, 'A', DISP_FGND_WHITE + DISP_BGND_BLUE + DISP_BLINK); 
* 
*              To have the ASCII character 'A' blink with a white letter on a blue background.
