3.4.2 Network registers

The list of registers below allows you to modify the network parameters of the product. This list is accessible in Provider mode following execu-
tion of the ATT63 Provider command.
These registers must be handled with caution because they could cause problems of communication or of non-compliance with the legislation
in force.
Register Description
S200 WMBUS channel
S201 Frame format
S221 AES mode
S222 AES key (first part –
MSB)
S223 AES key (second part –
MID MSB)
S224 AES key (third part –
MID LSB)
S225 AES key (fourth part –
LSB)
S227 WMBUS fields
Version and Device Type
Coding
Decimal Default: 24
Min/max: 0 to 33
Unit : none
See Note 1
Decimal Default: 1
Values:
• 0 : A-format
• 1 : B-format (minimize frame duration)
• 2 : 'Universal' (TX=B, RX=A+B)
Hexadecimal Default : 0x0000 (no AES)
Values:
• 0x0000 : no AES
• 0x0001 : AES128 with CBC. Using the key defined in registers S222 to S225
Note : Encryption of the set of bytes of the payload. Encryption is done in blocks
of 16 bytes. If a block is less than 16 bytes, the buffer is completed with 0xFF
before the AES calculation. There will be in this case transmission of additional
bytes.
Default: 0
Key coded on 32 characters. Each of the 4 registers contains 8 characters.
Eg:
Hexadecimal AES-KEY = 01020304050607080910111213141516
• S222 = 01020304
• S223= 05060708
• S224 = 09101112
• S225 = 13141516
Hexadecimal Default: 0x0056
Min/Max: 0x0000 to 0xFFFF
The MSB is the Device Type and the LSB is the Version.
Eg: S227=0x0056 :
- Device Type = 0x00
- Version = 0x56
These 2 fields can be modified by the user.
