The Internal exposure mode cannot be synchronized to an external event. If external
synchronization is needed then External or Mixed mode must be selected for Exposure Control.

External exposure control (command: LINE CTRL EXT)
The line period and integration time are controlled externally by the CC1 and CC2 input signals
at the Camera Link connector.
1)
CC1. Line control. The time between two rising edges of CC1 defines the line period.
2)
CC2. Integration control. There are three special cases of CC2:
A)
CC2 constantly low: the integration time will always be the minimum possible.
B)
CC2 constantly high: the integration time will always be the maximum possible.
C)
The integration time is from any rising edge of CC2 to the next rising edge of CC1 in
all the other cases.

*) The delay between CC2 rising edge to start of actual integration and delay between CC1 rising edge to end of integration
depends on the sensor clock frequency.
