AFE7920: updateFBNco operation

Part Number: AFE7920

I am using c-function 2.0 version.
TX and RX change well according to the set frequency, but FB does not change the frequency.

Set Nco of FB as shown below.
Please check if there is anything wrong.

updateFbNco(0, 0, 3840000, 0);

updateFbNco(0, 0, 3840000, 1);

updateFbNco(0, 0, 3840000, 2);

updateFbNco(0, 0, 3840000, 3);

 

 

updateFbNco(0, 1, 3840000, 0);

updateFbNco(0, 1, 3840000, 1);

updateFbNco(0, 1, 3840000, 2);
