9.2.1 EPS Timing (Programmable exposure common)

If the shutter mode is set at SM=1(Programmable Exposure (Common),

On the above table, 511L is FVAL interval on normal continuous mode
1) In partial scan and the vertical binning modes, if programmable exposure
value is larger than 511L, the programmable exposure value is used in this formula.
511L + 5L + (programmable exposure value – 511L) = programmable exposure value + 5L
2) In vertical binning mode, 1L is different from normal scanning. So, the minimum trigger interval will be
different.
Note: If the trigger of Active High is input through 10pin, dummy pulses must be applied
more than one time when the camera is activated.
