Via this register, the ED measurement time can be defined. In case
value 0 is chosen, the measurement time is compliant to the defini-
tion of the IEEE802.15.4b standard. In the 902-928 MHz band, the
measurement time equals 128us. For the 868 MHz band, this sym-
bol time equals 320us.
0x14
MODEM_ED
LQI Value, updated as a result of successful ED measurement.
R
The result of the ED measurement is available in this register.
The value is normalized and on average will be independent from
the ED measurement time (ED_AV_TIME). Note that the value of
MODEM_ED also depends on the content of ED_THRESH (0x2E).
0x15
MODEM_LQI
LQI Value, updated after complete frame reception.
R
During reception of a data packet, the correlation values of the
symbol mapping is accumulated and divided by the number of sym-
bols in the packets. The number is a normalized Link Quality Indi-
cation.
