8. GPIO (Inputs and outputs)
8.1. Overview
All input and output signals pass through the GPIO (General Purpose Input and Output) module.
The GPIO module consists of a Look-Up Table (LUT – Cross-Point Switch), 2 Pulse Generators
and a 12-bit counter. In the LUT, the relationship between inputs, counters and outputs is
governed by internal register set-up.

On the above block diagram, Trigger 0 is used for Exposure and Trigger 1 is used for Delayed
Readout. The Time Stamp Reset can reset the time stamp compliant with the GigE Vision
standard. This is used for ensuring the same time stamp if multiple cameras are used.
The blocks shown in the above diagram have the following functionalities:
