NOTE: When using an external frame sync and preset sequencing or superframing, the external
frame sync should be set to comply with ITR frame rate limits. If the external sync rate is too fast, the
camera will ignore syncs that come before the camera is ready

5.4.2.3.1.1.2 Frame Sync Starts Readout (FSSR)
Upon frame sync, the camera immediately transmits the data from the previous frame. The
integration period is then placed to meet ROIC requirements. This mode always operates in IWR
mode. This mode can be used with either internal or external frame sync at full frame rates.

5.4.2.3.1.2 Trigger Mode
A sequence consists of a series of frames. In Preset Sequencing, that series of frames can be any
number of any of the four presets. In Superframing, the series is one or zero frames from each
preset. In Single Preset, the series is simply one frame of the selected preset.
