T FIN E = fine_integration _time x (1/CLK_PIX)
TROW = line_length _pck x (1/CLK_PIX)
TFINE = fine_integration_time/clk_pix
The maximum allowed value for fine_integration_time is
line_length_pck - fine_integration_time_max_margin

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.
