5.2 Extended Operating Mode
The Extended Operating Mode is a hardware MAC accelerator and goes beyond the
basic radio transceiver functionality provided by the Basic Operating Mode. It handles
time critical MAC tasks requested by the IEEE 802.15.4-2003/2006 standard, such as
automatic acknowledgement, automatic CSMA-CA, and retransmission. This results in
a more efficient IEEE 802.15.4-2003/2006 software MAC implementation, including
reduced code size, and may allow the use of a smaller microcontroller.
The Extended Operating Mode is designed to support IEEE 802.15.4-2003/2006
standard compliant frames and comprises the following procedures:
Receive with Automatic Acknowledgement (RX_AACK) divides into the tasks:
• Frame reception and automatic FCS check
• Configurable addressing fields check
• Interrupt indicating address match
• Interrupt indicating frame reception if it passes frame filtering and FCS check
• Automatic acknowledgment (ACK) frame transmission if applicable
• Support of slotted acknowledgment using SLP_TR pin (used for beacon-enabled
operation)
Transmit with Automatic CSMA-CA and Retransmission (TX_ARET) divides into
the tasks:
• CSMA-CA, including automatic CCA retry and random backoff
• Frame transmission and automatic FCS field generation
• Reception of ACK frame (if ACK was requested)
• Automatic retry of transmissions if ACK was expected but not received or accepted
• Interrupt signaling with transaction status
An AT86RF212 state diagram, including the Extended Operating Mode states, is shown
in Figure 5-8. Yellow marked states represent the Basic Operating Mode; blue marked
states represent the Extended Operating Mode.
