Well, what I wanted to do was to store a value into the PIA register,
through a loop. I'm doing this in C, and to do a ROL you need to write
inline assembly. So I was trying to store a constantly changing value
into the register through a C assignment. That didn't work for me, for
some reason... I never got key presses... I'll retry it, though, maybe
I was doing it wrong the first time and didn't realize it.
