Block Diagram
Input of SGMODE controls synchronization mode between external synchronization mode and
internal. In the case of ext. sync. mode, HPA, VRR and ESR pulse should be supplied to sensor. On
the other hand, HD, VD and data clock is generated from sensor on int. sync. In that case electronic
shutter speed is controlled by command setting.

Note:
1) CMOS sensor can be operated under default setting value w/o sending command
2) Whole of setting command in same address should be set at the same time.
3) Electronic shutter control by command setting is available at internal synchronization mode. When external synchronization mode, ESR pulse input
can control electronic shutter speed.
