Iftheexposuretimeisgreaterthanaframereadouttime,theexposurestartsrstbypulsingtheGlobalClear.
The reference frame is read out during the exposure such that the end of the reference read out is coincident
with the end of the exposure. The Charge Transfer pulse then goes HIGH to transfer charge from all pixels in the
sensor. Finally, the signal frame is then read as shown below.
