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
- DB1 bit must be set to “1”.

When BID = "Low", segment data shift direction is set to normal order from SEG1 to SEG84.
When BID = "High", segment data shift direction is set to reverse from SEG84 to SEG1.
By using this instruction, the efficiency of application board area can be raised.
When B/W = "High", black/white inversion at the cursor position is set. In this case C/B bit of
display ON/OFF control instruction becomes don't care condition. If fOSC has frequency of
270kHz, inversion has 70 ms intervals.
Cursor Blink ON/OFF control bit
Display ON/OFF control bit
When D = "High", entire display is turned on.
When D = "Low", display is turned off, but display data is remained in DDRAM.
Cursor ON/OFF control bit
When C = "High", cursor is turned on.
When C = "Low", cursor is disappeared in current display, but I/D register remains its data.
When B = "High", cursor blink is on, that performs alternate between all the high data and
display character at the cursor position. If fOSC has 270 kHz frequency, blinking has 370 ms
interval.
When B = "Low", blink is off.
