SPECIFICATION (X23A-A-001-12)
Look-Up Table Registers
bits 7–0
LUT Address Bits [7:0]
These 8 bits control a pointer into the Look-Up Tables (LUT). The S1D13505 has three
256-position, 4-bit wide LUTs, one for each of red, green, and blue – refer to “Look-Up
Table Architecture” for details.
This register selects which LUT entry is read/write accessible through the LUT Data Reg-
ister (REG[26h]). Writing the LUT Address Register automatically sets the pointer to the
Red LUT. Accesses to the LUT Data Register automatically increment the pointer.
For example, writing a value 03h into the LUT Address Register sets the pointer to R[3].
A subsequent access to the LUT Data Register accesses R[3] and moves the pointer onto
G[3]. Subsequent accesses to the LUT Data Register move the pointer onto B[3], R[4],
G[4], B[4], R[5], etc. Note that the RGB data is inserted into the LUT after the Blue data
is written, i.e. all three colors must be written before the LUT is updated.
bits 7–4
LUT Data
This register is used to read/write the RGB Look-Up Tables. This register accesses the
entry at the pointer controlled by the Look-Up Table Address Register (REG[24h]) – see
above.
Accesses to the Look-Up Table Data Register automatically increment the pointer. Note
that the RGB data is inserted into the LUT after the Blue data is written, i.e. all three col-
ors must be written before the LUT is updated.
