I finally tested http://groups.yahoo.com/group/lpc2000/message/11515 on my
LPC2103, and it works.  The Philips Flash Utility gives the not so useful
error message "Cannot communicate with test board!" when I try a Download
Flash or erase a subset of the sectors.

The LPC2000 uses little endian, so the value should be stored like this:

0x1FC = 0x21
0x1FD = 0x43
0x1FE = 0x65
0x1FF = 0x87

This is not an error.
