de-asserted when RSSI is below the
14.10.4 Carrier Sense (CS)
same threshold (with hysteresis).
The Carrier Sense (CS) flag is used as a sync
word qualifier and for CCA. The CS flag can be
set based on two conditions, which can be
individually adjusted:
• CS is asserted when the RSSI is above
a programmable absolute threshold, and
