I/D
S
Set the moving direction of cursor and display.
I/D: Increment/decrement of DDRAM address (cursor or blink)
When I/D = "High", cursor/blink moves to right and DDRAM address is increased by 1.
When I/D = "Low", cursor/blink moves to left and DDRAM address is decreased by 1.
- CGRAM/SEGRAM operates the same as DDRAM, when read from or write to CGRAM/SEGRAM.
When S = "High", after DDRAM write, the display of enabled line by DS1 - DS4 bits in the shift enable instruction
is shifted to the right (I/D = "0") or to the left (I/D = "1"). But it will seem as if the cursor does not move. When S =
"Low", or DDRAM read, or CGRAM/SEGRAM read/write operation, shift of display like this function is not
performed.

BID
Set the data shift direction of segment in the application set.
BID: Data shift direction of segment
When BID = "Low", segment data shift direction is set to normal order from SEG1 to SEG100.
When BID = "High", segment data shift direction is set to reverse from SEG100 to SEG1.
By using this instruction, you can raise the efficiency of application board area.
- The BID setting instruction is recommended to be set at the same time level of function set instruction.
- DB1 bit must be set to "1".
