Trigger modi
The cameras support IIDC-conforming Trigger_Mode_0 and Trigger_Mode_1
and special Trigger_Mode_15.
Trigger_Mode_0 sets the shutter time according to the value set in the shut-
ter (or extended shutter) register. Trigger_Mode_1 sets the shutter time
according to the active low time of the pulse applied (or active high time in
the case of an inverting input).
