The carrier-sense operation detects if a signal is present, which has the following main purposes:
The carrier sense operation can be used with the command CMD_PROP_CS to chain with another operation (for example, a transmit operation), or with the commands CMD_PROP_RX_SNIFF or CMD_PROP_RX_ADV_SNIFF to combine with a normal receive operation in order to implement sniff mode. The details of these commands are described in Section 26.10.5.5.1, Section 26.10.5.5.2, and Section 26.10.5.5.3.
