Hi,
I've got rather basic question, and things don't add up to me... I hope it's the right forum.
If I have a screen of, let's say, 9 pixesl by 9 pixels.
Each of these 9 pixels can be represented by 4 bits, so the total address bus is 8 bits wide (both axes are 4 bits each).
Now, from a different point of view, the total sum of pixels is 81 pixels, and that is 7 bits wide...
So something is wrong here, obviously.
Please clarify.
Thx.
