Description

Operation mode

Fields

MODE

The mode of operation to be used. Settings in this register apply whenever either the KSGEN task or the CRYPT task is 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 keystream 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 keystream for packet payloads up to MAXPACKETSIZE bytes will be generated.
