This instruction makes CGRAM data available from MPU. 11) Set SEGRAM Address (RE = 1) RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 1 X X AC3 AC2 AC1 AC0 Set SEGRAM address to AC. This instruction makes SEGRAM data available from MPU. 12) Set DDRAM Address (RE = 0) RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 AC6 AC5 AC4 AC3 AC2 AC1 AC0 Set DDRAM address to AC. 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. 13) Set Scroll Quantity (RE = 1) RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 X SQ5 SQ4 SQ3 SQ2 SQ1 SQ0 As set SQ5 to SQ0, horizontal scroll quantity can be controlled in dot units. (refer to Table 9). In this case S6A0073 can show hidden areas of DDRAM by executing smooth scroll from 1 to 48 dots. Table 9.
