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.
Acting in pairs, Registers [2Ch], [2Dh] and registers [2Eh], [2Fh] are used to form the 16
bpp (5-6-5) RGB values for the two user defined colors.
Register [30h] determines the location in the display buffer where the cursor/ink layer will
be located. Table 7-2: can be used to determine this location.
