LUT Data
This register is used to read/write the RGB Look-Up Tables. This register accesses the entry at the
pointer controlled by the Look-Up Table Address Register (REG[24h]) – see above.
Accesses to the Look-Up Table Data Register automatically increment the pointer.Note that the
RGB data is inserted into the LUT after the Blue data is written, i.e. all three colors must be written
before the LUT is updated.
Ink/Cursor Control Bits [1:0]
These bits select the operating mode of the Ink/Cursor circuitry. See table below
Ink/Cursor FIFO Threshold Bits [3:0]
These bits specify the Ink/Cursor FIFO depth required to sustain uninterrupted display fetches.
When these bits are all 0, the Ink/Cursor FIFO depth is calculated automatically.
Reserved
This bit must be set to 0.
