9.5.4.4 Interrupt Handling
The TRX24_CCA_ED_DONE interrupt is issued at the end of a manually initiated ED
measurement.
Note that an ED request should only be initiated in one of the receive states. Otherwise
the radio transceiver generates a TRX24_CCA_ED_DONE interrupt but no ED
measurement was performed.
9.5.5 Clear Channel Assessment (CCA)
The main features of the Clear Channel Assessment (CCA) module are:
All 4 modes are available as defined by IEEE 802.15.4-2006 in section 6.9.9;
Adjustable threshold for energy detection algorithm.
9.5.5.1 Overview
A CCA measurement is used to detect a clear channel. Four modes are specified by
IEEE 802.15.4-2006:
Table 9-24. CCA Mode Overview
CCA Mode
Description
1
Energy above threshold
.
CCA shall report a busy medium upon detecting any energy above the ED
threshold.
2
Carrier sense only
.
CCA shall report a busy medium only upon the detection of a signal with the
modulation and spreading characteristics of an IEEE 802.15.4 compliant signal.
The signal strength may be above or below the ED threshold.
