R/W Preamble quality estimator threshold. The preamble quality
estimator increases an internal counter by one each time a bit is
received that is different from the previous bit, and decreases the
counter by 4 each time a bit is received that is the same as the
last bit. The counter saturates at 0 and 31.
A threshold of 4·PQT for this counter is used to gate sync word
detection. When PQT=0 a sync word is always accepted.
R/W
R/W Enable automatic flush of RX FIFO when CRC in not OK. This
requires that only one packet is in the RXIFIFO and that packet
length is limited to the RX FIFO size.
R/W When enabled, two status bytes will be appended to the payload
of the packet. The status bytes contain RSSI and LQI values, as
well as the CRC OK flag.
R/W Controls address check configuration of received packages.
Setting Address check configuration
0 (00) No address check
1 (01) Address check, no broadcast
2 (10) Address check, 0 (0x00) broadcast
3 (11) Address check, 0 (0x00) and 255 (0xFF) broadcast
