The cursor threshold bits are used to control the Ink/Cursor FIFO depth to sustain uninterrupted
display fetches.
Registers [28h] and [29h] control the horizontal position of the hardware cursor. The value in this
register specifies the location of the left edge of the cursor. When ink mode is selected these registers
should be set to zero.
Cursor X Position bits 9-0 determine the horizontal location of the cursor. With 10 bits of resolution
the horizontal cursor range is 1024 pixels.
Registers [2Ah] and [2Bh] control the vertical position of the hardware cursor. The value in this
register specifies the location of the left edge of the cursor. When ink mode is selected these registers
should be set to zero.
Cursor Y Position bits 9-0 determine the location of the cursor. With ten bits of resolution the
vertical cursor range is 1024 pixels.
