These registers are used to specify the (x,y) coordinate of the lower right corner of the cursor. All registers
are uninitialized and may be written to or read from by the MPU at any time.

The cursor-position X and Y values to be written are calculated as follows:
CPx = desired display screen x position for upper left corner of cursor + 0x40
CPy = desired display screen y position for upper left corner of cursor + 0x40
Values from 0 to 4095 (0xFFF) can be written into the cursor-position X and Y registers. The values written
into the cursor-position X and Y registers are the screen coordinates for the lower right corner of the cursor.
If zero is written to either the CPx or CPy registers, the cursor is positioned off screen. See Section 2.9.2.

The latch-control register definition is listed in Table 2–27.
