R0
Not used
4 RX_TIME_RSSI
0
R/W Direct RX termination based on RSSI measurement (carrier
sense).
3 RX_TIME_QUAL
0
R/W When the RX_TIME timer expires the chip stays in RX mode
if sync word is found when RX_TIME_QUAL=0, or either sync
word is found or PQT is reached when RX_TIME_QUAL=1.
2:0 RX_TIME[2:0]
111
R/W Timeout for sync word search in RX. The timeout is relative to
the programmed t_Event0.
The RX timeout in µs is given by EVENT0·C(RX_TIME, WOR_RES) ·26/X, where C is given by the table below and X is
the reference frequency (f_Ref) in MHz:
RX_TIME[2:0]
WOR_RES=0
WOR_RES=1
WOR_RES=2
WOR_RES=3

As an example, EVENT0 = 34666, WOR_RES = 0 and RX_TIME = 6 corresponds to 1.96 ms RX timeout
