 *	$Log:   P:/PVCS6_6/archives/LH7A400 (Aruba)/LCD/LH7A400_CLCDC_driver.h-arc  $
 * 
 *    Rev 1.4   Jan 09 2002 10:51:10   KovitzP
 * added bits per pixel functions
 * 
 *    Rev 1.3   Jan 09 2002 09:22:10   KovitzP
 * Added a number of functions. Changed the prefix of function
 * calls from clcdc to lcd because function calls use both the
 * CLCDC and the LCDICP; together, these IP blocks make up
 * the LCD controller system.
 * 
 *    Rev 1.2   Jan 07 2002 12:06:46   MaysR
 * Added support for LM057QCTT03 and LM5Q321 CSTN displays.
 *
 *    Rev 1.1   Nov 08 2001 18:14:58   SuryanG
 * No code change. Added file banner.
 *
 *
 *    Rev 1.0   Aug 13 2001 10:22:34   StokerD
 * Initial revision.

/*
   This file contains the defines for the various LCD displays controlled
   by the LH7A400. When a new display is added, the following steps have
   to be performed:
      1. Define all the constants using one of the display settings below
         as a template.
      2. Add the name of the new display to the display_type_t enumerated type
         at the end of the list and equate it to the value set on the dip switch
         Ensure that the enumerated type value and the dip switch settings are
         the same, otherwise, the initialization function will return an error.
      3. Add the corresponding constants into the lcd_settings structure.
      4. Pass the display type as a parameter to clcdc_init() function from
         your application first in code.
