4.4.1 Configuration Zone Addressing

The Configuration zone can be accessed either 4 or 32 bytes at a time. Individual bytes cannot be accessed. The Configuration zone address is a 2-byte (16-bit value). Only the lowest five bits of the address word are used in addressing of the Configuration zone. For the ATECC608B-TNGLoRaWAN device, these addresses can only be used with the Read command.
