Some special registers of BG0836 are implemented by the shadow registers. That is to
say, when these registers are written through the I2C, they will not automatically update
immediately. Updating these registers needs special operation, and these registers will
be specially explain later.

The pixel (0, 0) of BG0836 is near the A10 pin of the package as shown in Figure 1
Mechanical Drawing. The default horizontal readout direction is scanning from A10 to
A1. The default vertical readout direction is scanning from A10 to F10.
