LUT Write Address Bits [7:0]
This register is a pointer to the Look-Up Table (LUT) which is used to write LUT data
stored in REG[08h], REG[09h], and REG[0Ah].
The data is updated to the LUT only
with the completion of a write to this register
. This is a write-only register and
returns 00h if read.
Note
The SSD1905 has three 256-entry, 6-bit-wide LUTs, one for each of red, green and
blue (see Section 15 “Look-Up Table Architecture”).

LUT Blue Read Data Bits [5:0]
This register contains the data from the blue component of the Look-Up Table. The
LUT entry read is controlled by the LUT Read Address Register (REG[0Fh]).
Note
This register is updated only when the LUT Read Address Register (REG[0Fh]) is
written.

This register contains the data from the green component of the Look-Up Table. The
LUT entry read is controlled by the LUT Read Address Register (REG[0Fh]).
Note
This register is updated only when the LUT Read Address Register (REG[0Fh]) is
written.
