Configuration
The use of the Extended Operating Mode is based on Basic Operating Mode functionality. Only
features beyond the basic radio transceiver functionality are described in the following sections.
For details on the Basic Operating Mode refer to
33.
When using the RX_AACK or TX_ARET modes, the following registers needs to be configured.
RX_AACK configuration steps:
The addresses for the address match algorithm are to be stored in the appropriate address reg-
isters. Additional control of the RX_AACK mode is done with register 0x17 (XAH_CTRL_1) and
register 0x2E (CSMA_SEED_1).
As long as a short address has not been set, only broadcast frames and frames matching the
IEEE address can be received.
Configuration examples for different device operating modes and handling of various frame
types can be found in
TX_ARET configuration steps:

retransmissions.
The register bits MAX_CSMA_RETRIES (register 0x2C) configure the number of CSMA-CA
retries after a busy channel is detected.
• Short address, PAN-ID and IEEE address
• Configure RX_AACK properties
• Additional Frame Filtering Properties
• Leave register bit TX_AUTO_CRC_ON = 1
• Configure CSMA-CA
• Configure CCA (see
