I'm writing code for use on a Single Board computer. The board has an LED which I'm trying to turn on off, but I'm having some trouble understanding how to access it. The LED can be accessed at I/O location 77h bit 0. A logic "1" is the on condition (I'm assuming that logic "0" is the off condition). How do I access this specific bit? I've looked at several threads on this board and others, but haven't understood much of what I've read. Any help, direct or indirect, is much appreciated.
