The Galois field tables are mapped in the ROM just after the ROM code, as described in 

 below:

For a full description and an example of how to use the PMECC detection and correction feature, refer to the software 
package dedicated to this device on Atmel’s web site.

The SD Card bootloader uses MCI0. It looks for a “boot.bin” file in the root directory of a FAT12/16/32 formatted SD 
Card.

SD Card Boot supports all SD Card memories compliant with SD Memory Card Specification V2.0. This includes SDHC 
cards.
