Lpc2000

I use LPC2106 for my project, and have to store some data into
emulated EEPROM in flah using IAP. But I am not so shure about how
does IAP operations works and manual is lack of informations about
that. The thing I don't understand if I want to erase one sector (8 k)
will my program be able to continue, or I have to wait that IAP
operation finishes. I have the same question about write operation.

Thanks.
