The minimum frame-time is defined by the number of row periods per frame and the
row period. The sensor frame-time will increase if the coarse_integration_time is set to a
value equal to or greater than the frame_length_lines. The maximum integration time
can be limited to the frame time by setting R0x30CE[5] to 1.
