Hiya Guy's,
I'm on my next project using a 16f877a and I intend to use the 4 lower bits from portA to control the data lines in 4 bit mode. now the question is I can just label portA as lcd_data as is usually done, but what if I want to use the 2 remaing pins?. I've looked around on the net without finding any usefull answer so if someone can answer my query I'll appreciate it.
