The Ink image should always start at the top left pixel, i.e. Cursor X Position and Cursor Y
Position registers should always be set to zero. The width and height of the ink image are
automatically calculated to completely cover the display.
The Cursor image size is always 64 x 64 pixels. The Cursor X Position and Cursor Y
Position registers specify the position of the top left pixel. The following diagram shows
how to position an unclipped cursor.

For LCD:
x = (REG[073h] bits [1:0], REG[072h]) and REG[073h] bit 7 = 0
y = (REG[075h] bits [1:0], REG[074h]) and REG[075h] bit 7 = 0
For CRT/TV:
x = (REG[083h] bits [1:0], REG[082h]) and REG[083h] bit 7 = 0
y = (REG[085h] bits [1:0], REG[084h]) and REG[085h] bit 7 = 0
The following diagram shows how to position a cursor that is clipped at the top and left
