Lookup Table Structure in the Memory
This block is used to generate the pixel gray or color information in palletized configurations. The
different modes with the palletized/non-palletized configuration can be found in
these modes, 1, 2, 4 or 8 input bits index an entry in the lookup table. The corresponding entry in
the lookup table contains the color or gray shade information for the pixel.
Table 38-5.
The lookup table can be accessed by the host in R/W mode to allow the host to program and
check the values stored in the palette. It is mapped in the LCD controller configuration memory
map. The LUT is mapped as 16-bit half-words aligned at word boundaries, only word write
access is allowed (the 16 MSB of the bus are not used). For the detailed memory map, see
Table 38-12 on page
The lookup table contains 256 16-bit wide entries. The 256 entries are chosen by the program-
mer from the 2
For the structure of each LUT entry, see
In STN Monochrome, only the four most significant bits of the red value are used (16 gray
shades). In STN Color, only the four most significant bits of the blue, green and red value are
used (4096 colors).
In TFT mode, all the bits in the blue, green and red values are used (32768 colors). In this mode,
there is also a common intensity bit that can be used to double the possible colors. This bit is the
least significant bit of each color component in the LCDD interface (LCDD[18], LCDD[10],
LCDD[2]). The LCDD unused bits are tied to 0 when TFT palletized configurations are used
(LCDD[17:16], LCDD[9:8], LCDD[1:0]).
