Additional bandwidths can be selected with special settings described in section 7.2.8.
With additional bandwidth configuration register settings as described in sections 5.2.6 and 7.2.8.
SPR strongly depends on the design of the application board and the choice of the external components. Values down to -70 dBm can be
achieved with careful design.
304.7 kbit/s achievable with additional register settings as described in section 6. The 304.7kpbs max bit rate is guaranteed by validation.
The max bit rate guaranteed by production test is 152.3 kbit/s
RSSI also available in mode B with higher thresholds as described in section 5.2.3.4
