NVM Device Detection
The 82574L detects the device connected on the SPI interface in two phases.
In reference to the EEPROM, the 82574 detects the length of the address bytes by
sensing the signature at word 0x12. It then sets the NVADDS field in the EEC register.
The exact size of the NVM is fetched by the 82574 from word 0x0F and is stored in the
NVSize field in the EEC register. When operating with an EEPROM that has an invalid
signature, software can force the address length via the NVADDS field in the EEC
register. Controlling the address length enables software to access the EEPROM via the
parallel EERD and EEWR registers in all cases including invalid signature.
CRC Field
CRC calculation and management is done by software.
SMBus or NC-SI manageability

1. It first detects the device type by the state of the NVMT strapping pin.
2. It then looks at the NVM content depending on a valid signature in word 0x12 in the
