6.2.4. LVAL a-synchronous accumulation
The CV-A33CL has LVAL a-synchronous accumulations only. The accumulation will start 28

after the trigger leading edge. EEN will indicate the accumulation time. When the accumulation
stops after the selected shutter time, the LVAL phase is reset and restarted.

Fig. 16. LVAL a-synchronous accumulation
In CV-A33 with LVAL a-synchronous accumulation a new trigger can be input and start a new
exposure during the previous frame read out. But the exposure may not be finished before the
frame is read out. It makes it possible to have a trigger rate close to the frame rate.
The minimum trigger interval should be >(1FVAL + 1 LVAL).
