EEPROM Defaults
The signature value of 0xA5 is stored at address 0. A different signature value indicates to the
EEPROM controller that no EEPROM or an un-programmed EEPROM is attached to the device. In
this case, the hardware default values are used, as shown in

usage of these fields.
3.3
EEPROM Auto-Load
Certain system level resets (USB reset, 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 A5h is read from the first address, then the EEPROM controller will
assume that a programmed external Serial EEPROM is present.
Note: The USB reset only loads the MAC address.
