Description

RW CCAMODE

CCA mode of operation

EdMode

Energy above threshold

Will report busy whenever energy is detected above

CCAEDTHRES

CarrierMode

Carrier seen

Will report busy whenever compliant IEEE 802.15.4 signal is

seen

CarrierAndEdMode

Energy above threshold AND carrier seen

CarrierOrEdMode

Energy above threshold OR carrier seen

EdModeTest1

Energy above threshold test mode that will abort when first

ED measurement over threshold is seen. No averaging.

RW CCAEDTHRES

CCA energy busy threshold. Used in all the CCA modes

except CarrierMode.

Must be converted from IEEE 802.15.4 range by dividing by

factor ED_RSSISCALE - similar to EDSAMPLE register

RW CCACORRTHRES

CCA correlator busy threshold. Only relevant to

CarrierMode, CarrierAndEdMode, and CarrierOrEdMode.

RW CCACORRCNT

Limit for occurances above CCACORRTHRES. When not

equal to zero the corrolator based signal detect is enabled.
