sampled_cca	A sampled version of the CCA bit from demodulator. The value is updated whenever a SSAMPLECCA or STXONCCA strobe is issued.
sfd_sync	Pin is high when a SFD has been received or transmitted. Cleared when leaving RX/TX respectively. Not to be confused with the SFD exception.
tx_active	Indicates that FFCTRL is in one of the TX states. Active-high.
rx_active	Indicates that FFCTRL is in one of the RX states. Active-high.
ffctrl_fifo	Pin is high when one or more bytes are in the RXFIFO. Low during RXFIFO overflow.
ffctrl_fifop	Pin is high when the number of bytes in the RXFIFO exceeds the programmable threshold or at least one complete frame is in the RXFIFO. Also highduring RXFIFO overflow. Not to be confused with the FIFOP exception.
packet_done	A complete frame has been received. I.e., the number of bytes set by the frame-length field has been received.
rfc_xor_rand_i_q	XOR between I and Q random outputs. Updated at 8 MHz.
rfc_rand_q	Random data output from the Q channel of the receiver. Updated at 8 MHz.
rfc_rand_i	Random data output from the I channel of the receiver. Updated at 8 MHz
lock_status	1 when PLL is in lock, otherwise 0
pa_pd	Power amplifier power-down signal.
lna_pd	LNA power-down signal.
disabled	disabled
