entered with µs precision via the EXTENDED_SHUTTER register.
The minimum allowed exposure time depends on the camera model. To deter-
mine this value write 1 to the ExpTime field and read back the minimum
allowed exposure time.
The longest exposure time, 3FFFFFFh, corresponds to 67.11 seconds.

Note

• Exposure times entered via the 81Ch register are mir-
rored in the extended register, but not vice versa.
• Changes in this register have immediate effect, even
when camera is transmitting.
• Extended shutter becomes inactive after writing to a
format / mode / frame rate register.
• Extended shutter setting will thus be overwritten by
the normal time base/shutter setting after Stop/Start
of FireView or FireDemo.
