Triggered Mode
In triggered mode, image acquisition begins with the rising edge of an external trigger pulse. The
image is read out after the pre-set exposure time. After readout, the sensor resets and the camera
waits for a new trigger pulse. The data is output on the rising edge of the pixel clock.
The signals FRAME_VALID (FVAL) and LINE_VALID (LVAL) mask valid image information.
The number of clock pulses after exposure CPRE is defined by the calculation of the frame time
(see section 1.12 Calculating Frame Rate).
