Display Control (R07h)
Figure 14Display Control
VLE2–1:
When VLE1 = 1, a vertical scroll is performed in the 1
st
screen. When VLE2 = “1”, a vertical
scroll is performed in the 2
nd
screen. Vertical scrolling on the two screens can be independently
controlled.
SPT:
When SPT = 1, the 2-division LCD drive is performed. For details, see the Screen-division
Driving Function section.
B/W:
When B/W = “1”, displayed data can be “all” or “all off” regardless GRAM contents. (B/W = “1”,
REV = “0”: all pixel on, B/W = “1”, REV = “1”: all pixel off) When B/W = “1”, grayscale palette has to
be default value.
REV:
Displays all character and graphics display sections with reversal when REV = 1. For details, see
the Reversed Display Function section. Since the grayscale level can be reversed, display of the same
data is enabled on normally-white and normally-black panels.
D1–0:
Display is on when D1 = “1” and off when D1 = 0. When off, the display data remains in the
GRAM, and can be displayed instantly by setting D1 = “1”. When D1 is “0”, the display is off with all
of the SEG/COM pin outputs set to the GND level. Because of this, the HD66766R can control the
charging current for the LCD with AC driving.
When D1–0 = “01”, the internal display of the HD66766R is performed although the display is off.
When D1-0 = “00”, the internal display operation halts and the display is off.

Notes: 1. Writing from the microcomputer to the GRAM is independent from the state of D1–0.
2.
In the sleep and standby modes, D1–0 = 00. However, the register contents of D1–0 are not modified.
