Most programmers and debuggers are responsible for calculating the signature word and putting it into the flash. The Philips flash programmer certainly does this as does my Signum JetJTAG. If your programmer does not, then you will need to calc it yourself. I think that is covered in the LPC210x manual. Chris.
