CAM1_CN and CAM1_CP

These pins provide the clock pulse for the MIPI data lanes for the first camera. They connect to the MIPI Clock Positive (MCP) and MIPI Clock negative (MCN) pins of the camera IC. These clock signals usually arrive from the camera module generated by the MIPI circuitry.


CAM1_DN0 and CAM1_DP0

These are the MIPI Data Positive (MDP), and MIPI Data negative (MDN) pins for the data lane 0 of camera 1.

CAM1_DN1 and CAM1_DP1

These are the MIPI Data Positive (MDP), and MIPI Data negative (MDN) pins for the data lane 1 of camera 1.

SCL0 and SDA0

A smaller serial bus consisting of SCL and SDA pins facilitates serial communication, which allows the user to control the camera functions such as selecting the resolutions. These pins connect directly to the SCCB slave interface inside the camera IC.

The SCL pin provides a standard serial interface clock input, and SDA standard serial interface for data I/O.
