The signal to indicate the end of the image dump frame is shown in Figure 10 below where pix end state is followed by a
low in both MISO_SDA and EVENT_INT. This will inform the Host of the pixel end and frame end state.
Figure 10. Frame End
Note: It is advisable to have a counter at the Host to keep count of the number of pixel addresses and data byte. If the number of pixel data byte does
not correspond to the sensor number of pixel then this image dump data is invalid. In this case the sensor must be reset and a new image dump must
be initiated.
