CCA_STATUS (register 0x01, TRX_STATUS) are updated after a CCA_REQUEST. The regis-
ter bit is automatically cleared after requesting a CCA measurement with CCA_REQUEST = 1.
• Bit [6:5] - CCA_MODE
The CCA mode can be selected using register bits CCA_MODE.
Table 8-12.
Note that IEEE 802.15.4-2006 CCA Mode 3 defines the logical combination of CCA Mode 1 and
2 with the logical operators AND or OR. This can be selected with:
• Bit [4:0] - CHANNEL
Refer to
Register 0x09 (CCA_THRES):
This register sets the ED threshold level for CCA.
• Bit [7:5] - Reserved
• Bit [4:0] - CCA_ED_THRES
The CCA Mode 1 request indicates a busy channel if the measured received power is above
RSSI_BASE_VAL + 2 * CCA_ED_THRES [dBm]. CCA Modes 0 and 3 are logical related to this
result.
