8.0 FRONT-END PROCESSING
All the parameters in this section refer to the programmability of the FE part of the device
(registers). The part of the registers that are not described here have either fixed values (shown
in the tables with a black background) or values written by the tuner drivers, and therefore not
directly by the user (shown in the tables with a red background, if the registers are written
exclusively by the tuner drivers, and with orange background if they can be written by the user
for the manual FE alignment operation). The user can write the FE registers through the
dedicated commands, and must take care that the fixed values sent through such means are as
indicated in the tables below. After modifying a register containing at least one red background
bit, the user should send again the set band, set frequency and set image rejection commands
for proper operation.
