S1D13708 Hardware Functional Specification
X39A-A-001-02 Issue Date: 02/03/07
bits 7-2 LUT Red Write Data Bits [5:0]
This register contains the data to be written to the red component of the Look-Up Table.
The data is stored in this register until a write to the LUT Write Address register
(REG[0Bh]) moves the data into the Look-Up Table.
Note
The LUT entry is updated only when the LUT Write Address Register (REG[0Bh]) is
written to.
bits 7-0 LUT Write Address Bits [7:0]
This register forms a pointer into the Look-Up Table (LUT) which is used to write LUT
data stored in REG[08h], REG[09h] and REG[0Ah. The LUT Read Address Register
(REG[0Fh]) and all corresponding Read Data Registers will also be updated with the
newly written address and data. This is a write-only register and returns 00h if read.Fh
Note
The S1D13708 has three 256-position, 6-bit wide LUTs, one for each of red, green, and
blue (see Section 11, “Look-Up Table Architecture” on page 173).
bits 7-2 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]). This is a read-
only register.
