HD66773R
REV: When REV = 1, a reverse display is shown. Inverting the grayscale levels allows the display of
same data on both normally white and normally black panels. The source output level is as follows.

GON: When GON = 0, the gate-off level is VGH.
D1–0: The graphics display is on when D1 = 1, and off when D1 = 0. When setting D1 = 0, the data are
retained in GRAM. This means the graphics is instantly redisplayed when setting D1 to 1. When D1 is 0
(i.e., the display is off) all the source outputs are set to the GND level. This reduces the charged/discharged
current during liquid crystal AC drive.
When D1-0 = 01, the HD66773R continues internal display operation, even while the external display is
off. When D1-0 = 00, both internal and external display operation are halted.
In combination with GON and DTE bits, D1-0 bits control ON/OFF of display. For details, see “Instruction
Setting Flow”.
