2.5.7 Flash Trigger Signal

This signal can be programmed via the FlashCtrl register (see section 4.2.4.14). Six different
options are programmable:
• The FlashOut trigger signal can be deactivated, that is, low.
• It can be tied to an "Effective Exposure" signal that is generated internally. This means that
the FlashOut signal goes high when exposure starts and it goes low when exposure stops,
regardless of the exposure mode chosen. As an option, the polarity of FlashOut can be
inverted.
• The signal can be tied to the external ExFlash input signal provided by the framegrabber. As
an option, the polarity of FlashOut can be inverted.
• FlashOut can be permanently high.
