Registers 15-17 (exposure time)
The exposure time is stored in three (15 – 17) 8 bit registers (24 bits total).
The exposure time is set in increments of the pixel clock. For the 1M28, each increment is
35 ns. For the 1M75, each increment is 50 ns. The final exposure time can be calculated by
changing the stored binary value to a decimal value and multiplying by the time of the
appropriate increment for your camera.
