I²C-bus control bits:
OFTS(1 : 0) = 00 (subaddress 10H, bits D7 and D6).
RGB888 = 1 (subaddress 12H, bit D3).

16.1 Layout hints
Use separate ground planes for analog and digital ground.
Connect these planes at one point directly under the
device, by using a zero Ω resistor. Use separate supply
lines for analog and digital supply. Place the supply
decoupling capacitors close to the supply pins.
Place the coupling (clamp) capacitors close to the analog
input pins. Place the termination resistors close to the
coupling capacitors. Care should be exercised concerning
the hidden layout capacitors around the crystal
application. To avoid reflection effects use serial resistors
in the clock, sync and data lines.
