Register 0x02 - CCA Control
CCA1, CCA0 - 802.11 CCA Mode:
RSSI_t - 6-bit RSSI threshold value for CCA.
Register 0x03 - Diversity and RSSI Value
* - Read Only
NOTE: The six (6) LSB’s are read-only and reflect the receiver status.
Diversity - RX diversity enable bit.
Default - 0
0 - No diversity, ANT SEL pin is forced to Cpantsel.
1 - Diversity active, RF3000 automatically selects ANT SEL pin.
Cpantsel - Antenna selection bit in non-diversity mode.
Default - 0
0 - ANT SEL forced to 0.
1 - ANT SEL forced to 1.
RSSI5-0 - Output of the RSSI A/D - Read Only
Register 0x04 - RX Signal Field (Read only)
In DSSS modes, this value is the received byte of the received signal field. In FHSS, only the four (4) LSB’s are used.
*** - IEEE802.11b proposed modulation rates not currently supported.
Register 0x05 - RX Length Field MSB’s (Read only)
The upper byte of the length field received.
In DSSS mode, this value is the length in microseconds of the received data packet.
