User manual
Pixel data values can be written and verified through the AHB slave interface. For
information on the supported colors, refer to the section on the related panel type earlier in
this chapter.
The palette RAM is a dual port RAM with independent controls and addresses for each
port. Port1 is used as a read/write port and is connected to the AHB slave interface. The
palette entries can be written and verified through this port. Port2 is used as a read-only
port and is connected to the unpacker and gray scaler. For color modes of less than 16
bpp, the palette enables each pixel value to be mapped to a 16-bit color:
Table 12–250
uses the TFT 1:5:5:5 data format. In 16 and 24 bpp TFT mode, the palette is bypassed
and the output of the pixel serializer is used as the TFT panel data.
Table 250. Palette data storage for TFT modes.
The red and blue pixel data can be swapped to support BGR data format using a control
register bit (bit 8 = BGR). See the LCD_CTRL register description for more information.

For TFT displays, the 16-bit value is passed directly to the pixel serializer.
For STN displays, the 16-bit value is first converted by the gray scaler.
