tTransfer
The tim e from the recep tion of the falling ed ge of EXSYN C to the rising
ed ge of LVAL w hen p retrigger is set to zero. Pretrigger red u ces the
number of clocks to the rising ed ge of LVAL but d oesn’t change the time to
the first valid p ixel. If the fixed integration tim e m od e of operation is
available and selected then the integration tim e is ad d ed to the sp ecified
