The Pi camera module based on OV5647 has a number of external pins, VSYNC, STROBE and FREX.

How do I use these pins? In particular I want to synchronize the camera to an IMU, will the Strobe pin toggle at the start of every frame? How does the vsync work? Can I further control camera settings in relation to these pins in a driver?
VSYNC: Frame synchronization signal, VSYNC will output a level jump signal every time a frame of image is transmitted.
STROBE and FREX pin functions refer to the following pictures.
Thank you! Sorry I got busy.
