(1)

The in-line streaming mode is a special case, dedicated to readout with v

ery small window sizes for “line

scan

”-like applications. As it differs quite a lot from the other control modes, it is only mentioned here for

completeness' sake and will be further detailed in section 7.8.2.

Each of these control modes is introduced in one of the following sections.

Control Mode 0: Full External

In the Full External control mode, the exposure timing is fully controlled with the sensor input

pins:

●

A rising edge on REQ_EXP moves the sensor to the EXPOSURE state

●

A rising edge on REQ_FRAME moves the sensor to the GLOB state, which will be

automatically followed by READOUT.

The length of the EXPOSURE state will exactly match the time between the rising edges of

both triggers.

In the figure below, the state diagrams of sequential and pipelined operation are annotated

with the external control events.
