Page 10 of the user manual UM10108 SFR 0xDB is I2ADR

But something is definitely wrong. I still haven't got to the bottom of it, but I found a Keil example that I stuffed into the LPC and it worked no worries so I know that it is code now, which is a great relief.

I have to find out where the issue is and why my emulator works and the board doesn't (with my code anyway)

BTW

I would find it very surprising if the LPC9XX series changed the names of the SFR's between models in the same family. surely that is just making work for yourself. I was on the understanding that the LPC9xx series grew in functionality as the model numbers (and legs) increased. No changes in the instructions or SFR's other than ommissions where the functionality is not included obviously.
