5. Scroll display mode
The scroll display mode is entered by setting registers SBIT0 to 3
(SA), SLIN0 to 4 (SB), SST0 to 4 (SC), and SEND0 to 4 (SD) (all
at address 2AE16). (Scroll is turned off when SD = 0.)
The screen is scrolled in the range from the (SC)’th line to the
(SD-1)’th line, and sections above and below this range are fixed.
The beginning line and beginning dot of scroll are the (SA)’th dot
on the (SB)’th line.
The screen can be scrolled up or down by successively
incrementing or decrementing SA and SB.
Figure 6 shows examples of how the display is scrolled. The scroll
range in these examples contains 12 lines (second to the 13th lines).
However, the screen can display only 11 lines at a time, and the
re-maining one line is handled as a dummy line and not displayed.
Fig. 6 Scrolling example
When displayed in order of SA = 0, 1, 2, and so on, the screen scrolls up. When displayed in order of SA = 12, 11, 10, and so on, the
screen scrolls down.
(1) To scroll the screen up, write the dummy line after you set the 0th dot in SA but before setting the 1st dot.
(2) To scroll the screen down, write the dummy line after you set the 0th dot in SA but before setting the 12th dot of the preceding line.

SB = 5
SC = 2
SD = 14
