hello..
I have problem with serial programming p89v51rd2, because the micro-controller what I brought from market is working properly only for 2-3 time programming, after that if i want to program it, the flash magic shows the message that "reset the device into isp mode now" then pressing the reset button, nothing happens...
i had also programmed a lot of p89v51rd2 on the same board successfully, now i think the micro-controller what i brought from market are duplicate...
I can use only the p89v51rd2. i have no idea how to program it parallel.
please help me to parallel programming of p89v51rd2.
