Table 103: Color look-up table register, subaddress FFh, bit description
Data byte Description
COLSA RAM start address for color LUT; the byte following subaddress FFh points to the
first cell to be loaded with the next transmitted byte; succeeding cells are loaded by
auto-incrementing until stop condition
