Operation and Signaling
Digital Signals
Depending on the operation mode (Master or Slave), the pixel array of the image sensor requires different digital control signals. The
function of each signal is listed in this table.

Synchronous Shutter
In a synchronous (snapshot or global) shutter, light integration occurs on all pixels in parallel, although subsequent readout is
sequential. Figure 7 shows the integration and readout sequence for the synchronous shutter. All pixels are light sensitive at the same
period of time. The whole pixel core is reset simultaneously, and after the integration time, all pixel values are sampled together on
the storage node inside each pixel. The pixel core is read out line by line after integration. Note that the integration and readout cycle
can occur in parallel or in sequential mode (pipelined or triggered). Refer to the section Image Sensor Timing and Readout on page 18.
