#120146 - ambiguity regarding ports in 80C51/80C52 |
Hello,
I am new to 80C52 controllers. This is required for my current project. For an I/O pin, we require two information: one is the direction information -- whether it is input or output; the other is the data -- whether it is zero or one. Till now, i found that only port latch is available. Kindly clarify this point at the earliest. Best Regards, Manoj |
