End of exposure to first packet on the bus
After the exposure, the CCD sensor is read out; some data is written into the
FRAME_BUFFER before being transmitted to the bus.
The time from the end of exposure to the start of transport on the bus is:
710 μs ± 62.5 μs
This time jitters with the cycle time of the bus (125 μs).
