Lpc2000

The IAP interface supports programming of blocks that are 512, 1024, 
2048, 4096, 8192 bytes.
Since the IAP routines are used by most programmers this means that your 
application is padded with zeros, 0xFF or junk depending on the 
implementation of the programmer. The size of the padding depends on the 
block size used by the programmer.

Richard.
