Then increment SN2 to SN0 to 001, and again increment SL2 to SL0 by 1 from 000 to 111. To start
displaying and scrolling from the first raster-row of the second line, update the first line of DDRAM data as
desired during its non-display period.
Figure 41 shows an example of vertical smooth scrolling and Figure 42 shows an example of setting
instructions for vertically scrolling upward in a 4-line display (NL1 and NL0 = 11).
Update the first line of DDRAM data
9) 8 raster-rows scrolled
up
· SN2–SN0 = 001
· SL2–SL0 = 000
Set initial data to all DDRAM addresses
1) Not scrolled
· SN2–0 = 000
· SL2–0 = 000
2) 1 raster-rows scrolled
up
· SL2–SL0 = 001
3) 2 raster-rows scrolled
up
· SL2–SL0 = 010
4) 3 raster-rows scrolled
up
· SL2–SL0 = 011
5) 4 raster-rows scrolled
up
· SL2–SL0 = 100
6) 5 raster-rows scrolled
up
· SL2–SL0 = 101
7) 6 raster-rows scrolled
up
· SL2–SL0 = 110
10) 9 raster-rows scrolled
up
· SL2–SL0 = 001
11) 10 raster-rows scrolled
up
· SL2–SL0 = 010
12) 11 raster-rows scrolled
up
· SL2–SL0 = 011
13) 12 raster-rows scrolled
up
· SL2–SL0 = 100
14) 13 raster-rows scrolled
up
· SL2–SL0 = 101
15) 14 raster-rows scrolled
up
· SL2–SL0 = 110
16) 15 raster-rows scrolled
up
· SL2–SL0 = 111
8) 7 raster-rows scrolled
up
· SL2–SL0 = 111
