Point Grey Flea3 GigE - GPIO Modes; GPIO Mode 0: Input; GPIO Mode 1: Output; GPIO Mode 2: Asynchronous (External) Trigger

Point Grey Flea3 GigE Technical Reference 6 Input/Output Control
6.2 GPIO Modes
6.2.1 GPIO Mode 0: Input
When a GPIO pin is put into GPIOMode 0 it is configured to accept external trigger signals. See Serial Communication.
6.2.2 GPIO Mode 1: Output
When a GPIO pin is put into GPIOMode 1 it is configured to send output signals.
Do not connect power to a pin configured as an output (effectively
connecting two outputs to each other). Doing so can cause damage to
camera electronics.
6.2.3 GPIO Mode 2: Asynchronous (External) Trigger
When a GPIO pin is put into GPIO Mode 2, and an external trigger mode is enabled (which disables isochronous data
transmission), the camera can be asynchronously triggered to grab an image by sending a voltage transition to the pin.
See Asynchronous Triggering.
6.2.4 GPIO Mode 3: Strobe
A GPIO pin in GPIO Mode 3 outputs a voltage pulse of fixed delay, either relative to the start of integration (default) or
relative to the time of an asynchronous trigger. A GPIOpin in this mode can be configured to output a variable strobe
pattern. See Programmable Strobe Output.
6.2.5 GPIOMode 4: Pulse Width Modulation (PWM)
When a GPIO pin is set to GPIO Mode 4, the pin outputs a specified number of pulses with programmable high and low
duration. See Pulse Width Modulation (PWM).
