2.4.4 phyCCAMode Macro

#define phyCCAMode (0x03)

This macro holds The CCA mode

• CCA Mode 1: Energy above threshold. CCA shall report a busy medium

upon detecting any energy above the ED threshold.

• CCA Mode 2: Carrier sense only. CCA shall report a busy medium only upon

the detection of a signal with the modulation and spreading characteristics of IEEE 802.15.4. This signal may be above or below the ED threshold.

• CCA Mode 3: Carrier sense with energy above threshold. CCA shall report a

busy medium only upon the detection of a signal with the modulation and spreading characteristics of IEEE 802.15.4 with energy above the ED threshold.
