BYTE
Certain system level resets (USB reset, POR, nRESET, and SRST) cause the EEPROM contents to
be loaded into the device. After a reset, the EEPROM controller attempts to read the first byte of data
from the EEPROM. If the value 0xA5 is read from the first address, then the EEPROM controller will
assume that an external Serial EEPROM is present.
Note: The USB reset only loads the MAC address.
