4) Display ON/OFF Control ( RE = 0 )
Control display/cursor/blink ON/OFF 1 bit register.
D : Display ON/OFF control bit
C : Cursor ON/OFF control bit
B : Cursor Blink ON/OFF control bit
display character at the cursor position. If fosc has 270 kHz frequency, blinking has 370 ms interval.
5) Extended Function Set ( RE = 1 )
FW : Font Width control
becomes 6/5 times than that of 5-dot font width.
the leftmost space bit of CGRAM.(Refer to Fig-10)
B/W : Black/White Inversion enable bit
of display ON/OFF control instruction becomes don't care condition. If fosc has frequency of
270 kHz, inversion has 370 ms intervals.
NW : 4 Line mode enable bit
becomes don't care condition.






























When D = "High", entire display is turned on.
When D = "Low", display is turned off, but display data is remained in DDRAM.
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
When B = "Low", blink is off.
When FW = "High", display character font width is assigned to 6-dot and execution time
When FW = "Low", 5-dot font width is set.
When B/W = "High", black/white inversion at the cursor position is set. In this case C/B bit
When NW = "High", 4 line display mode is set. In this case N bit of function set instruction
The user font, specified in CGRAM, is displayed into 6-dot font width, bit-5 to bit-0,including
