6.4.5 Pulse width control (PWC) mode
In this mode, the user has full control of both the line rate and the exposure time of each line
via the External Trigger input.
At the rising edge of the External Trigger signal, the exposure is initiated, and at the falling
edge the exposure is terminated and read out. The camera can accept an external trigger
through the Camera Link connector or through the 12-pin Hirose connector.

the camera must receive continuous external trigger pulses corresponding to the frequency
and duty cycle used in the application.
