For 16 bpp color depth, the Display Data Byte Swap bit (REG[71h] bit 6) must be set
to 1.
For 16 bpp color depth, the MSB of the 16-bit pixel data is stored at the even system
memory address location and the LSB of the 16-bit pixel data is stored at the odd system
memory address location. Bus data byte swapping (automatic when the S1D13706 is
configured for Big-Endian) causes the 16-bit pixel data to be stored byte-swapped in the
S1D13706 display buffer. During display refresh this stored data must be byte-swapped
again before it is sent to the display.
