Does it possible to access the external programming memory during during the program is running in the internal memory of 8052. (EA/Vpp change to GND while the program wanna jump to the external memory and EA/Vpp change back to +5V power supply if it wanna jump back to the internal memory??)
I wanna download a assembly program during the program in 8052 is running and run it...
If not, how can I do that??
