7.5 LNA Intermodulation Control Register
7.5.1
LNA IM Control: $14 – 8-bit write only
This register controls features of the receiver that support intermodulation optimisation. All bits of this
register are cleared to ‘0’ by a General Reset command.

b7,6 reserved, clear to ‘0’
b5-0 These bits allow the user to adjust the intermodulation performance of the LNA. The default value is
‘0’ for all the bits. Improved intermodulation can be achieved with a particular value in these bits.
For further details see section 8.1.4.
7.5.2 LNA IM Control: $E4 – 8-bit read only
This read-only register mirrors the value in register $14; see section 7.5.1 for details of bit functions.
