R/W
0 : IEEE 802.15.4 compliant mode

00 : Normal operation, transmit TXFIFO
01 : Serial mode, use transmit data on serial interface,
infinite transmission.

CCA_THR[7:0]
0xE0
R/W
The unit is 1 dB, offset is TBD [depends on the absolute
gain of the RX chain, including external components and
should be measured]. The CCA signal goes high when the
received signal is below this value.
The reset value is in the range of -70 dBm.
