6.2.8. LVAL a-synchronous accumulation

With LS=1, the accumulation will start immediately after the trigger leading edge. The exposure start delay will be 156 clk. pulses after the trigger. It is 3.9 ∝sec.

In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL). In PWC mode the exposure stops 0.5 L after the trigger trailing edge.

A new trigger must not be applied before the previous frame is read out. (FVAL is low). The minimum trigger interval should be longer than the exposure time + 1 FVAL+3 LVAL.

Important notes on using this mode.

In LVAL a-synchronous PWC mode there is no exposure jitter.
