37.5.2.4 Serializer
This block serializes the data read from memory. It reads words from the FIFO and outputs pixels (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 37-3 and
Table 37-4.
