/**    IAP : internal Flash memory access library
 *
 *        The internal Flash memory access is described in the LPC1768 usermanual.

 *            Chapter  2: "LPC17xx Memory map"
 *            Chapter 32: "LPC17xx Flash memory interface and programming"
 *                refering Rev. 01 - 4 January 2010

 *        revision 1.0  09-Mar-2010   1st release
 *        revision 1.1  12-Mar-2010   chaged: to make possible to reserve flash area for user
 *                                            it can be set by USER_FLASH_AREA_START and USER_FLASH_AREA_SIZE in IAP.h
