boot block is present at addresses 0x0007 D000 to 0x0007 FFFF in all devices. ISP and
IAP commands do not allow write/erase/go operation on the boot block. Because of the
boot block, the amount of Flash available for user code and data is 500 K bytes in "512K"
devices. On the other hand, in case of the LPC2141/2/4/6 microcontroller all
32/64/128/256 K of Flash are available for user's application.

21.6 Flash content protection mechanism
The LPC2141/2/4/6/8 is equipped with the Error Correction Code (ECC) capable Flash
memory. The purpose of an error correction module is twofold. Firstly, it decodes data
words read from the memory into output data words. Secondly, it encodes data words to
be written to the memory. The error correction capability consists of single bit error
correction with Hamming code.
