In pixelbinning mode the value of rC is internally
doubled. The value must not be higher than
1ffh/511.
6.17.2.2 Leftmost pixel of the trigger line
The value of register r8 / 10 is the number of the leftmost pixel in the trigger line.

Response: none
Calculation of r8:
Value of r8 = pixel number / 10
