23.7.5.5.2 Carrier-Sense Command, CMD_PROP_CS
When the carrier-sense command starts, the radio is set up in receive mode, and the operations described
in Section 23.7.5.5.1, Common Carrier Sense Description, are performed. The radio must be set up in a
compatible mode (such as proprietary mode) and the synthesizer programmed using CMD_FS.
If the trigger given by csEndTrigger and csEndTime is observed, the operation ends, and the current
channel state is checked. If the state is BUSY or IDLE, the status is PROP_DONE_BUSY or
PROP_DONE_IDLE, respectively. If the state is INVALID, the status depends on csConf.timeoutRes. If 0,
the status is PROP_DONE_BUSYTIMEOUT; if 1, PROP_DONE_IDLETIMEOUT.
When CMD_PROP_CS ends and the status is PROP_DONE_BUSY or PROP_DONE_BUSYTIMEOUT,
the synthesizer is turned off if csFsConf.bFsOffBusy is 1. If the command ends and the status is
PROP_DONE_IDLE or PROP_DONE_IDLETIMEOUT, the synthesizer is turned off if csFsConf.bFsOffIdle
is 1. If it ends with another status, the synthesizer is turned off if either of these bits is 1.
The end statuses for use with CMD_PROP_CS are summarized in
next operation, as in
Condition
Observed channel state BUSY with nonzero csConf.busyOp
Observed channel state IDLE with nonzero csConf.idleOp
Timeout trigger observed with channel state BUSY
Timeout trigger observed with channel state IDLE
Timeout trigger observed with channel state INVALID and csConf.timeoutRes =
0
Timeout trigger observed with channel state INVALID and csConf.timeoutRes =
1
Observed illegal parameter
