21. X/Y Conversion
The X/Y conversion rotates a 16 x 16 matrix data by 90 degrees and also inverts 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 registers XiR and YjR from an
even address in 16-bit units. Performance cannot be guaranteed if registers XiR and YjR are accessed in 8-bit units.
Figure 21.1
The XYC0 bit in the XYC register determines how to read the YjR register.
When setting the XYC0 bit to 0 (data converted) and reading the YjR register, all the bits j in registers X0R to X15R
can be read.
For example, bit 0 in the X0R register can be read when reading bit 0 in the Y0R register, bit 0 in the X1R register
when reading bit 1 in the Y0R register..., bit 0 in the X14R register when reading bit 14 in the Y0R register, and bit 0
in the X15R register when reading bit 15 in the Y0R register.
Figure 21.2 shows a conversion table when the XYC0 bit is set to 0. Figure 21.3 shows an example of the X/Y
conversion.
