This block serializes the data read from memory. It reads words from the FIFO and outputs pix-
els (1 bit, 2 bits, 4 bits, 8 bits, 16 bits or 24 bits wide) depending on the format specified in the
PIXELSIZE field of the LCDCON2 register. It also adapts the memory-ordering format. Both big-
endian and little-endian formats are supported. They are configured in the MEMOR field of the
LCDCON2 register.
The organization of the pixel data in the memory depends on the configuration and is shown in
Table 39-3
Note:

For a color depth of 24 bits per pixel there are two different formats supported: packed and
unpacked. The packed format needs less memory but has some limitations when working in 2D
addressing mode
