Arducam Hat External Trigger

Is there any way to synchronize the arducam hat with an external trigger? I know the global shutter cameras have them but I didn’t see the option for the hat board. Additionally is there a way to get close to the exact sampling time of the camera image(or at least start or end of sampling)?

Or is there a way to access to the arducam hat local oscillator and have it serve as a time base for other things like an IMU?



Like a single global shutter camera, the binocular board also has an external trigger signal.
