Reg 0x109 control the index of the full table gain. Is it correct ?
What about the Mixer subtable gain. What is the register that control the index of the 16 values table ?
You should not program the registers differently. These registers are programmed by the function ad9361_load_gt when you load a gain table into the chip.
We recommend to use API for reading back the gain. Refer to the below link:
It is not possible to control the mixer or the other component gains independently. You can use split table mode in which you can control the LMT and the LPF gain independently.
Of course it is possible to control the gain independently, we do it !
We wanted to know what is the register that control the index of the mixer subtable gain as reg0x109 for the ful/spilt table gain.
Is it possible to have this information ?
Yes. Gain change is only done by incrementing or decrementing gain index in gain table. If you need to change only mixer gain , you need to edit the gain table for same and use corresponding gain index.
There is no direct way to configure mixer gain with register.
So which register control the gain index of the Mixer subtable ?
They is no register or control pin to control the gain index of the mixer.
