P89V51Rx2/P89LV51Rx2 / Re: IAP routine for P89V51RD2
March 20, 2009, 07:16:41 PM
Hi,
   I am working on P89V51RC2 and also have problem to make the IAP work.
-> calling the PGM_MTP vector is ABOVE 2000h.
May I ask you how to deal with this problem? The spec also mention that
avoid clearing BSEL when executing user code within the range 0000 to 1fffh.
However, I think for small testing program, the place to call IAP must be
inside this range. Do we have to do some extra work in main function
or IAP routine? Thank you so much.
