XY conversion rotates the 16 x 16 matrix data by 90 degrees. It can also be used to invert the top and
bottom of the 16-bit data. Figure 24.1 shows the XY control register.
The Xi and the Yi registers are 16-bit registers. There are 16 of each (where i= 0 to 15).
The Xi and Yi registers are mapped to the same address. The Xi register is a write-only register, while the
Yi register is a read-only register. Be sure to access the Xi and Yi registers in 16-bit units from an even
address. Operation cannot be guaranteed if you attempt to access these registers in 8-bit units.
