I am new to microcontroller programming, and am about to lay hands on the 8051 AT89C51.
I want to do some basic things like flashing LEDs, microcontroller to microcontroller data exchange etc.
I have no intention to use external memory or things like that. So, I have no work with the ALE or PSEN pins. I have learnt that in this case I have to connect the EA pin to VCC.
Now my question is, what do I do with the PSEN and ALE pin connections. Do I leave them unconnected, ground, or connect them to VCC?
