Is there any way to access the onboard EEPROM on the LPC11U24 ?

From the spec sheet of the 11u24 family, it looks like they all have some small amount of EEPROM built into them (1K-4K), is there a way to access this through a library or a good reason to not be allowed to use this feature of the 11u24 in the MBED config ?

Just found the answer, thanks to work done by Suga KouBou, he provided code to use the 11U24 IAP routines to access the eeprom, thank you Suga.

And it actually works like a charm, I've thrown away my AT45DB04 for the internal eeprom, reducing cost and complexity. Lerche

Hello, I use also the IAP function to write the EEPROM on an LPC11U24. it works fine, but I found an issue : I'm using at the same time a virtual com port on USB, and I found that the IAP EEPROM write call sometime (but rarely) never returns if the USB interrupt is enabled. Since I turned off the interrupt before the call, and back on after, the problem never occured again. Hope this helps. PP
