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-TNGTLS device, these addresses can only be used with the read command.

Table 4-4. Address Format
Byte 1: Addr[15:8]	Byte 0: Addr[7:0]
Unused	Unused	Block	Offset
Addr[15:8]	Addr[7:5]	Addr[4:3]	Addr[2:0]
