Note_1: The Node ID 0 value cannot be set to 0xFF and 1st bit of Node ID 0 can not be set to “1” (i.e. cannot be set to
multicast MAC address).
Note_2: The correct value of eFuse Checksum field must be equal to (0xFF - SUM [eFuse offset 00h ~ 1Fh excluding eFuse
Checksum field]). If SUM [eFuse offset 00h ~ 1Fh excluding eFuse Checksum field] has carry, please add ‘1’ to its
result.
