Note
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.
Ink/Cursor Start Address Bits [7:0]
Bit 7 is write only, when reading back the register this bit reads a ’0’.
