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
5) Extended Function Set ( RE = 1 )
FW : Font Width control
B/W : Black/White Inversion enable bit
NW : 4 Line mode enable bit
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 display character at the
cursor position. If fosc has 270 kHz frequency, blinking has 370 ms interval.
When B = "Low", blink is off.
When FW = "High", display character font width is assigned to 6-dot and execution time becomes 6/5 times than that
of 5-dot font width. The user font, specified in CGRAM, is displayed into 6-dot font width, bit-5 to bit-0,including the
leftmost space bit of CGRAM.(Refer to Fig-10)
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
of display ON/OFF control instruction becomes don't care condition. If fosc has frequency of
270 kHz, inversion has 370 ms intervals.
When NW = "High", 4 line display mode is set. In this case N bit of function set instruction
becomes don't care condition.
