Figure 7-8 Flow Diagram of TX_ARET
Figure 7-9 shows a TX_ARET transaction with the related timing. In this example a data
frame of length 10 with ACK request is transmitted. Furthermore the following
constrains are assumed:
• Register bits MIN_BE (register 0x2E) are set to 0 to not delay the execution of the
CCA algorithm after the rising edge at pin SLP_TR
• A clear channel is assumed (no CSMA-CA retry, no frame retransmission).
