The CMD_IEEE_CCA_REQ command takes a command structure as defined in Table 26-70.
CMD_IEEE_CCA_REQ must only be sent while an RX or energy-detect scan operation is running. On reception, the radio CPU writes the following figures back into the command structure:
If no valid RSSI is found when the request is sent, the currentRssi and maxRssi returned indicate this by using a special value (0x80).
If the command is issued without an active or suspended background-level RX operation, the radio CPU returns the result ContextError in CMDSTA. Otherwise, the radio CPU returns DONE.
