1. An endoscopic system for use in a light deficient environment comprising:
an endoscope comprising an image sensor, wherein the image sensor comprises a plurality of bidirectional data pads;
a control circuit in electronic communication with the image sensor;
wherein electronic communication through each of the bidirectional data pads is performed in a frame period, wherein the frame period is defined in four phases comprising:
a first phase where non-pixel data is issued from the image sensor through the bidirectional data pads;
a second phase during which internal timing signals, synchronization data, and readout of pixel data is output from the image sensor through the bidirectional data pads;
a third phase where non-pixel data is issued from the image sensor through the bidirectional data pads; and
a fourth phase during which image sensor configuration data and commands are received by the image sensor through the bidirectional data pads;
wherein clock signal data is transmitted during the first phase, the third phase, and the fourth phase of the frame period, but not during the second phase when pixel data is readout.
