AT89C51ED2: Selecting external vs internal flash

Alexandra Carey

I would like to set a (fuse?) bit to select the external Flash/PEROM as program memory instead of default Flash internal to the AT89C51. Is the BLJB bit the one I want to set? How do I set it?

    FC03 is wrong. The correct address is F800, according to my data sheet.

    I do not use Atmel and thus do not know if "FC03 is wrong", but the source of FC03 could be a PHILIPS data sheet. Philips cured some "chip errors" of goinig into ISP by making FC00 a jump to 0 so runaway programs did no cause a report of a chip malfunction.
