The X/Y conversion rotates a 16 x 16 matrix data by 90 degrees and inverses high-order bits and low-order
bits of a 16-bit data. Figure 21.1 shows the XYC register.
The 16-bit XiR register (i=0 to 15) and 16-bit YjR register (j=0 to 15) are allocated to the same address. The
XiR register is a write-only register, while the YjR register is a read-only register. Access the XiR and YjR
registers from an even address in 16-bit units. Performance cannot be guaranteed if the XiR and YiR
registers are accessed in 8-bit units.
