Microcontroller › 8051 › only 8051
hi
i was working on a circuit based on an 8051 microcontroller. 89C52 to be precise. till date my program wasn’t executing at all. the program counter wasn’t moving ahead. i had connected the ALE pin (pin 30) to ground and after floating it, the circuit was running fine.
so whats the problem??? you will have to coneect the ALe pin to high…
