32 / 78 page  S6A0073 34COM/60SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD 32 7) Cursor or Display Shift (RE = 0) RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 1 S/C R/L - - Shift right/left cursor position or display without writing or reading of display data. This instruction is used to correct or search display data (refer to Table 7). During 2-line mode display, cursor moves to the 2nd line after 40th digit of 1st line. In 4-line mode, cursor moves to the next line, only after every 20th digit of the current line. Note that display shift is performed simultaneously in all the line enabled by DS1 - DS4 in the Shift Enable instruction. When displayed data is shifted repeatedly, each line shifted individually. When display shift is performed, the contents of address counter are not changed. During low power consumption mode, display shift may not be performed normally. Table 7. Shift Patterns according to S/C and R/L Bits S/C R/L Operation 0 0 Shift cursor to the left, ADDRESS COUNTER is decreased by 1 0 1 Shift cursor to the right, ADDRESS COUNTER is increased by 1 1 0 Shift all the display to the left, cursor moves according to the display 1 1 Shift all the display to the right, cursor moves according to the display 8) Shift/Scroll Enable (RE = 1) (1) DH = 0 RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 1 HS4 HS3 HS2 HS1 HS : Horizontal Scroll per Line Enable. This instruction makes valid dot shift by a display line unit. HS1, HS2, HS3 and HS4 indicate each line to be dot scrolled, and each scroll is performed individually in each line. If you want to scroll the line in 1-line display mode or the 1st line in 2-line display mode, set HS1 and HS2 to "High". If the 2nd line scroll is needed in 2-line mode, set HS3 and HS4 to "High". (refer to Table 8) (2) DH = 1 RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 1 DS4 DS3 DS2 DS1 DS : Display Shift per Line Enable. This instruction selects shifting line to be shifted according to each line mode in display shift right/left instruction. DS1, DS2, DS3 and DS4 indicate each line to be shifted, and each shift is performed individually in each line. If you set DS1 and DS2 to "High" (enable) in 2 line mode, only the 1st line is shifted and the 2nd line is not shifted. When only DS1 = "High", only the half of the 1st line is shifted. If all the DS bits (DS1 to DS4) are set to "Low" (disable), no display is shifted. |
