Table 8-9.
Note:
It is recommended to perform CCA measurements in RX_ON state only. To avoid switching
accidentally to BUSY_RX state the SHR detection can be disabled by setting register bit
RX_PDT_DIS (register 0x15, RX_SYN), refer to
receiver remains in RX_ON state to perform a CCA measurement until the register bit
RX_PDT_DIS is set back to continue the frame reception. In this case the CCA measurement
duration is 8 symbol periods.

1. After receiving the SHR an automated ED measurement is started with a length of 8 symbol
periods (PSDU rate 250 kb/s), refer to
automated ED measurement must be finished to provide a result for the CCA measurement.
Only one automated ED measurement per frame is performed.
CCA Measurement Period and Access in BUSY_RX state
Carrier sense with Energy above threshold (AND).
CCA result is available after finishing
automated ED measurement period.
Carrier sense with Energy above threshold (OR).
CCA result is available after finishing
automated ED measurement period
