RCT mode

8.7.1 RCT mode
Until the trigger is input, the camera operates continuously and can use auto-gain, if necessary, to
control the exposure setting. During this time, FVAL and LVAL are output but DVAL is not output. When
the trigger is input, the fast dump is activated to read out the electronic charge very quickly, after which
the accumulation and the readout are performed. When the accumulated signal against the trigger is
read out, FVAL, LVAL and DVAL are output too.
Primary settings to use this mode
