C EEPROM Devices
When writing to an MMIO register address, there is no endian mode issue. The msbit
of the word ‘V’
SDRAM address there is an endian mode issue. Depending on the current endian
mode
DRAM gate
To retrieve the boot script, the Boot module performs the following I
The interpretation of this sequence by 2048 bytes or smaller EEPROMs is:
Hence, for a 2048-byte or smaller EEPROM, the boot image must start at byte 1.
The interpretation of this sequence by 4096 bytes or larger EEPROMs is:
Hence, for a 4096-byte or larger EEPROM, the boot image must start at byte 0.

In little-endian mode, the MSB of ‘V’ (or the last read EEPROM byte of the word),
end up in memory byte address ‘A+3’ and LSB (or first read EEPROM byte), end
up at the byte address ‘a’.
In big-endian mode, the MSB of ‘V’ (or last read EEPROM byte), end up at the
byte address ‘A’ and the LSB (or first read EEPROM byte), end up at the byte
address ‘A+3’.

Write a byte value 0 to address 0 (setting the next address-pointer to byte
address 1).
Read, starting from address 1.
Write a 0 byte-long sequence to address 0 (setting next address pointer to byte
address 0).
Read, starting from address 0.
