WMBUS channel
Decimal
Default: 24
Min/max: 0 to 33
Unit: None
See note 1
201
Frame format
Decimal
Default: 1
Possible value:
• 0: format A
• 1: format B (reduces the duration of the frame)
• 2: ‘Universal’ (TX=B, RX=A+B)
221
AES mode
Hexadecimal
Default: 0x0000 (no AES)
Possible value:
• 0x0000: no AES
• 0x0001: AES128 with CBC. Using the key defined in the
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.
222
AES Key (first part - MSB)
Hexadecimal
Default: 0
Key coded on 32 characters. Each of the 4 registers con-
tains 8 characters.
Example :
AES-KEY = 01020304050607080910111213141516
• S222 = 01020304
• S223= 05060708
• S224 = 09101112
• S225 = 13141516

WMBUS Version and Device Type Fields
Hexadecimal
Default: 0x0056
Min/Max: 0x0000 to 0xFFFF
The MSB represents the Device Type and the LSB Version.
Example: S227=0x0056 :
- Device Type = 0x00
- Version = 0x56
These 2 fields can be modified at will by the user.
