Scroll Line. Scroll the displayed image up by SL rows. The valid SL value is
between 0 (for no scrolling) and (79– 2xFL). Setting SL outside of this range
causes undefined effect on the displayed image.
Fixed Lines. The first FLx2 lines of each frame are fixed and are not
affected by scrolling (SL). When FL is non-zero, the screen is effectively
separated into two regions: one scrollable, one non-scrollable.
When partial display mode is activated, the display of these 2xFL lines is
also controlled by LC[0].
Return Column Address. Useful for cursor implementation.
