Note:
exposure time (set) command, the allowable exposure time increments listed above also
apply to exposure mode 4 (Smart EXSYNC) or 6 when exposure time overlaps frame
readout. This is because, in exposure mode 4, the falling edge is captured by the camera
every 18.513 µs for example in the case of clm 15 or 16
4 or 6 the exposure time effectively has an uncertainty of the allowable time increment.
Refer to section 3.4 Exposure Correction for more information on the clm and sot (sets
pixel rate) commands.
Refer to section Figure 10: Mode 2 on page 29 for an example where exposure time
overlaps frame readout.
