5) Cursor or Display Shift
Table 4. Shift Patterns According to S/C and R/L bits
6) Function Set
DL : Interface data length control bit
N : Display line number control bit
F : Display font type control bit
When DL = “1”, it means 8-bit bus mode with MPU.
When DL = “0”, it means 4-bit bus mode with MPU. So to speak, DL is a signal to select
When N = “0”, it means 1-line display mode.
When N = “1”, 2-line display mode is set.
When F = “0”, 5
When F = “1”, 5
Without writing or reading the display data, shift right/left cursor position or display.
This instruction is used to correct or search display data.(Refer to Table 4)
During 2-line mode display, cursor moves to the 2nd line after the 40st digit of the 1st line.
Note that display shift is performed simultaneously in all the lines.
When displayed data is shifted repeatedly, each line shifts individually.
When display shift is performed, the contents of the address counter are not changed.
8-bit or 4-bit bus mode.
When 4-bit bus mode, it needs to transfer 4-bit data in two parts.
