Hi, Tolera
I read the timing of line scan camera. I think you need following signals as below.
AOUT: to a ADC port(J7-1, PTB0)
SI: To a GPIO(J7-3, PTB1)
SCLK: a FTM port.(J7-10, PTC1)
In your read mode, you can use ADC to read convert data on FTM input capture happened. You can also use GPIO to check SI high or low.
Hope my reply can help you.
Best Regards
Paul
