 * Description:
 *      This file contains the structure definitions and manifest
 *      constants for component:
 *
 *          Color LCD Controller
 *
 *  Note (1): Several LCD macros calculate a value by subtracting
 *      1 or 2 from an argument.  The programmer is responsible for
 *      ensuring that the argument is >= 1 or >= 2, as applicable.
