B:
The character indicated by the cursor blinks when B is 1. The blinking is displayed as switching
between all black dots and displayed characters every 32 frames. The cursor and blinking can be set to
display simultaneously. When LC and B = 1, the blinking is displayed as switching between all white dots
and displayed characters.

D:
Display is on when D is 1 and off when D is 0. When off, the display data remains in DDRAM, and can
be displayed instantly by setting D to 1. When D is 0, the display is off with the SEG1 to SEG72 (96)
outputs, COM1 to COM24 outputs, and COMS1/2 output set to the GND level and off. Because of this, the
HD66724/HD66725 can control charging current for the LCD with AC driving.
CEN:
Switches the common driver position from COM1 to COM8. When CEN = 1, it outputs the first line
of COM1 to COM8 in the center of the screen. For details, see the Partial-Display-On Function section.
LC:
When LC = 1, a cursor attribute is assigned to the line that contains the address counter (AC) value.
Cursor mode can be selected with the B/W, C, and B bits. Refer to the Line-Cursor Display section.
