I have lost 3 hours, but this is too complicated for me to find all details needed to control in assembler 8 LEDs.
Please, write me in steps what should I do. I expect, that after some initialization switching on and off some LED will be as simple as setting/clearing one bit.
P.S. Every time I try to use a new resource I have to check and read too many documents and places.
This is the worst documentation I have ever seen.
