LUT Red Read Data Bits [5:0]
This register contains the data from the red 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.
LUT Read Address Bits [7:0]
This register is a pointer to the Look-Up Table (LUT) which is used to read LUT data
and store it in REG[0Ch], REG[0Dh], REG[0Eh]. The data is read from the LUT only
when a write to this register is completed. This is a write-only register and returns
00h if read.
Note
The SSD1908 has three 256-entry, 6-bit-wide LUTs, one for each of red, green and
blue (see Section 15 “Look-Up Table Architecture”).
