Hello Ralf, 
 
                      I agree with you that external eeprom is an option, but we have a choice to use NV-area of LPC so that overall cost of broad can come down significantly. Yes, but care to be taken that it erase 8KB sector. 
 
 Tom  IAP functions are to be used to stroed internally. 
 
thanks,
 
Sridhar

Hi Tom,
I'm using 2106 and 2114 and I think the only possible way to store 
internal data is to use the IAP function. But than you will use minimum 
an 8kB flash sector to store only one byte. Important is also, that you 
can only erase the whole 8kB sector completely. for storing data in a nv 
area I use an extern I2C eeprom.
Regards,
Ralf
