Making an application updateable using IAP in P89LPC936?

Hi all,
I was wondering whether it is possible to make my application firmware updateable using IAP. I readed some application notes but did not become much wiser, if any of you could help me with this.
Best regards

  • After calling the IAP, is the chip then in the ISP mode?
    You are mixing ISP/IAP anyhow, after eithet do a reset.

    how to make a simple boot which is able to manupulate the bytes such that the data is currupted to the outside world while downloading to the chip and then manupulating the data back to the original in that simple boot.
    A boot is a mistake, the '51 derivatives are Read Only Program Memory intended, so once you have loadedthe program you are set
