2.3.18.8 Cursor-Color 0, 1 RGB Registers (Index 23 – 28 hex)
These registers are used to specify the two colors for the hardware cursor (see Section 2.3.9). Note that
there are six registers total, three for each color. The register formats for both the cursor-color 0 and
cursor-color 1 registers are shown below.

Index = 25 and 28 (hex)
Values 00 (hex) to FF (hex) can be written into the cursor-color registers at any time.
2.3.18.9 Cursor-RAM Address LSB and MSB Registers (Index 08 – 09 hex)
These registers are used to specify the address of where to write or read sprite cursor data. The nonplanar
addressing scheme is depicted in Figure 2–10 of Section 2.3.9.1. The registers are not initialized and can
be accessed by the MPU at any time. Bits D2–D7 are always a logic zero.

Values from 0000 (hex) to 03FF (hex) can be written into the cursor-RAM address registers.
When the cursor-RAM address is to be written, both registers must be written with the cursor-RAM LSB
address written first.
