It is necessary to program this register only if AGC
settings, other than the defaults, are required.
In receive mode, AGC is set to automatic AGC by default
on power-up. The default thresholds are AGC_ LOW_
THRESHOLD = 30 and AGC_HIGH_ THRESHOLD = 70.
See the RSSI/AGC section for details.

AGC high and low settings must be more than 30 apart to
ensure correct operation.
An LNA gain of 30 is available only if LNA_MODE
(R9_DB25) is set to 0.
