âCursor or Display Shiftâ Instruction
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
CODE 0 0 0 0 0 1 S/C R/L X X
The instruction above will shift the display and/or move the cursor one character to the left or right,
without DDRAM reading or writing.
âS/Câ Bit selects between the movement of both cursor and display or the movement of the cursor
alone. When âS/Câ=â1â the cursor and the display are both shifted. When âS/Câ=â0â only the cursor is
shifted.
The âR/Lâ Bit selects the left or right movement direction of the cursor and/or display. When âR/Lâ=â1â
the cursor and/or display is shifted one character to the right. When âR/Lâ is â0â the cursor and/or
character is shifted to the left.
