DTE:
When DTE = 0, the DISPTMG output is fixed to GND.

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 on LCD, accompanied by the liquid crystal AC drive.
When D1-0 = 01, the HD66787 continues the internal display operation, even while the external display is
off. When D1-0 = 00, both the internal display operations and the external display operation are halted.
In combination with GON and DTE bits, D1-0 bits control ON/OFF of display. For details, see the
“Instruction Setting Flow” section.

Note 1) Data are written to GRAM from the microcomputer irrespective of the setting of D1-0 bits.
Note 2) In the standby mode, D1-0 = "00". However, the D1-0 register setting before entering standby
modes is retained.

FP3-0/BP3-0:
Make settings for blank periods (the front and back porches), which are placed at the
beginning and end of the display. FP3-0 and BP3-0 bits specify the number of raster-rows for the front and
back porch respectively. When making this setting, make sure:
BP + FP = <16 raster-rows
FP >= 2 raster-rows
BP >= 2 raster-rows
In the external display interface mode, the back porch (BP) starts on the falling edge of VSYNC signal,
