00002  *  Sample of ISP operation for NXP MCUs
00003  *
00004  *  @author  Tedd OKANO
00005  *  @version 1.2.1
00006  *  @date    Aug-2015
00007  *
00008  *  This program programs MCU flash memory through UART. It uses
00009  *  "In-System Programming (ISP)" interface in target MCU (NXP LPC micro-
00010  *  controllers).
00011  *
00012  *  The ISP is done by PC and serial cable normally. The ISP protocol is
00013  *  executed software on a PC. The software reads a data file and transfers
00014  *  the data with the ISP protocol.
00015  *  This program does same process of that. The mbed perform the function like
00016  *  "FlashMagic" and "lpc21isp".
00017  *  (This program not just copies the binary but also insert 4 byte checksum at
00018  *  address 0x1C.)
00019  *
00020  *  This program supports 
00021  *      LPC1114, LPC1115, LPC81x, LPC82x, LPC1768/1769 and LPC11U68/LPC11E68. 
00022  *
00023  *  All detailed history is available in code publishing page. 
00024  *  Please find it on 
00025  *    https://developer.mbed.org/users/okano/code/ika_shouyu_poppoyaki/shortlog
00026  *  Thank you for all feedbacks and controbutes!
