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).
