Figure 2-13: 8 Bit Output Mode with Programmable Exposure for the A501k
2.5.8 Flash Trigger Signal
This signal can be programmed via the FlashCtrl register (see section 4.2.4.16). Six different
options are programmable:
• The FlashOut trigger signal can be deactivated, that is, be set to low.
• It can be tied to an “effective exposure“ signal (Integrate Enabled) generated internally. This
means that the FlashOut signal goes high when effective exposure starts and it goes low
when effective 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 frame grabber. As
an option, the polarity of FlashOut can be inverted.
• FlashOut can be permanently high.
