KS0074
11) Set DDRAM Address (RE = 0)
Set DDRAM address to AC.
12) Set Scroll Quantity (RE = 1)
Setting SQ5 to SQ0, horizontal scroll quantity can be controlled in dot units. (Refer to Table 12).
In this case of KS0074 execute dot smooth scroll from 1 to 48 dots.
Table 12. Scroll quantity according to HDS bits
This instruction makes DDRAM data available from MPU.
In 1-line display mode (N = 0, NW = 0), DDRAM address is from "00H" to "4FH".
In 2-line display mode (N = 1, NW = 0), DDRAM address in the 1st line is from "00H" to "27H", and DDRAM address in the
2nd line is from "40H" to "67H".
In 4-line display mode (NW = 1), DDRAM address is from "00H" to "13H" in the 1st line, from "20H" to "33H" in the 2nd line,
from "40H" to "53H" in the 3rd line and from "60H" to "73H" in the 4th line.
