• Description: LUPA-300 CMOS Image Sensor
• Manufacturer: CYPRESS [Cypress Semiconductor]

In case non destructive readout is used, the pulses on the input
pins still need to be given. By setting the NDR bit to "1" the
internal pixel reset pulses are suppressed but the external pulses
are still needed to have the correct timing of the frame transfer.
Readout Timing
The sensor is readout row by row. The LINE_VALID signal shows
when valid data of a row is at the outputs. FRAME_VALID shows
