LUT Address
The LUT address register selects which of the 256 LUT entries will be accessed. After three
successive reads/writes to the data register this register is automatically incremented to
point to the next address.
LUT Data
This register is where the 4-bit red/green/blue data value is written/read. Immediately after
setting the LUT index with register [15h] this register accesses the red element of the Look-
Up Table. With each successive write/read the internal bank select is incremented. Thus the
second access is from the green element and the third is from the blue element.
After the third access the LUT Address is incremented by one, then next access to this
register will be the red element of the next Look-Up Table index.
