There are two ways the radio can update the RSSI register after it has first become valid. If FRMCTRL0.ENERGY_SCAN = 0 (default), the RSSI register contains the latest value available, but if this bit is set to 1, a peak search is performed, and the RSSI register contains the largest value since the energy scan was enabled.
