LENGTH=Default, MODE=Encryption, DATARATE=1Mbit
Operation mode
MODE | The mode of operation to be used. The settings in this register apply whenever either the KSGEN or CRYPT tasks are triggered. 0 (Encryption): AES CCM packet encryption mode 1 (Decryption): AES CCM packet decryption mode |
DATARATE | Radio data rate that the CCM shall run synchronous with 0 (1Mbit): 1 Mbps 1 (2Mbit): 2 Mbps 2 (125Kbps): 125 Kbps 3 (500Kbps): 500 Kbps |
LENGTH | Packet length configuration 0 (Default): Default length. Effective length of LENGTH field in encrypted/decrypted packet is 5 bits. A key-stream for packet payloads up to 27 bytes will be generated. 1 (Extended): Extended length. Effective length of LENGTH field in encrypted/decrypted packet is 8 bits. A key-stream for packet payloads up to MAXPACKETSIZE bytes will be generated. |
