This register contains the result of an Energy Detection measurement.
Bit 7:0 – ED_LEVEL7:0 - Energy Detection Level
The minimum ED value (ED_LEVEL = 0) indicates a receiver power less than or equal
to RSSI_BASE_VAL. The range is 83 dB with a resolution of 1 dB and an absolute
accuracy of ±5 dB. A manual ED measurement can be initiated by a write access to this
register. A value of 0xFF signals that no measurement has yet been started (reset
value). The measurement duration is 8 symbol periods (128 s) for a data rate of 250
kb/s. For High Data Rate Modes the automated measurement duration is reduced to 32
s. For manually initiated ED measurements in these modes the measurement period is
still 128 s as long as the receiver is in RX_ON state. A value other than 0xFF indicates
the result of the last ED measurement.
