5.3.7 GPIO
This is a general interface for input and output and controls input and output for trigger
signals or valid signals and pulse generators. By using this interface, you can control an
external light source, make a delayed function to input a trigger signal or make a precise
exposure control with PWC trigger.
Basic block diagram is as follows.
