I did some experiment on the HW trigger mode and found some unexpected issue:
1. when I use HW trigger in sub-frame, advFrameCfg 4 0 1 2 0. when power is on, and i think it will wait until pulse at SYNC_IN pin comes. But in bin flash mode, I put no pulse signal, but the the sensor starts automatically and did not wait for pulse.
2. when I work in CCS debug mode, it will wait until pulse is detected.
3. When I set HW trigger mode, when I set sub frame interval is 23ms, the pulse interval is 25ms, and i found that, when i turn on pulse generator, the LVDS output is at 25ms interval, and when i turn pulse generator off, lvds output is at 23ms interval.
so confused.
