Description
When set, this bit disables the on-chip LNA AGC system, powers down unused circuitry, and locks the LNA to maximum
gain. The user must set Reg 20, bit 6=1 to enable writes to Reg 0x2E. It is recommended to set this bit during
initialization to save power.
These bits are reserved and should be written with zeros.
