4) Entry Mode Set
? (RE = 0)
Set the moving direction of cursor and display.
I/D : Increment / decrement of DDRAM address (cursor or blink)
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.
@ (RE = 1)
Set the data shift direction of segment in the application set.
BID : Data Shift Direction of Segment
* 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".
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 BID = "Low", segment data shift direction is set to normal order from SEG1 to SEG80.
When BID = "High", segment data shift direction is set to reverse from SEG80 to SEG1.
By using this instruction, the efficiency of application board area can be raised.
