6. Input and output interface
6.1. 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), 4 Pulse Generators and a
12-bit counter. In the LUT, the relationship between inputs, counters and outputs is governed by
internal register set-up.

6.1.1 LUT (Cross point switch) input and output setting
The LUT works as a cross-point switch, which allows connecting inputs and outputs freely. The
signals LVAL_IN, DVAL_IN, FVAL_IN and EEN_IN all originate from the camera timing circuit.
Trigger 0 is connected to the camera's timing circuit and is used for initiating triggered exposure.
Trigger 1 is used for Delayed Readout mode. The Time Stamp Reset signal is used reset the
camera's time stamp function, also making it possible to reset and synchronize the time stamp of
multiple cameras.
