+/**    IAP : internal Flash memory access library
+ *
+ *        The internal Flash memory access is described in the LPC1768 usermanual.
+ *            http://www.nxp.com/documents/user_manual/UM10360.pdf
+ *
+ *            Chapter  2: "LPC17xx Memory map"
+ *            Chapter 32: "LPC17xx Flash memory interface and programming"
+ *                refering Rev. 01 - 4 January 2010
+ *
+ *        Released under the MIT License: http://mbed.org/license/mit
+ *
+ *        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
