Display On/Off Control
D:
Display is on when SW = 0 and D = 1 and off when D = 0. When off, the display data remains in the
DDRAM or CGRAM, and can be displayed instantly by setting D = 1. When D is 0, the display is off with
the SEG1 to SEG112 outputs and COM1 to COM80 outputs set to the GND level. Because of this, the
HD66728 can control charging current for the LCD with AC driving.
LC:
When SW = 0 and LC = 1, a cursor attribute is assigned to the line that contains the address counter
(AC) value. Cursor mode can be selected in the black-and-white reversed display, underline display, and
blink display with the B/W, C, and B bits. For details, see the Line-cursor Display section.
DL10:
When SW = 0, DL10 can be set. When DL10 = 1, the 10th line is displayed at double height.
DL9–DL7:
When SW = 1, DL9–DL7 can be set. Double-height display is specified for any display line.
When DL7 = 1, the seventh line is displayed at double height. Double-height display is used for the eighth
line when DL8 = 1 and for the ninth line when DL9 = 1. For double-height display for the first to the sixth
lines, control them by using DL1–DL6 bits in the display-line control instruction.
