+MIPI CCS Embedded Data Formats
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+`MIPI CCS <https://www.mipi.org/specifications/camera-command-set>`_ defines an
+metadata format for sensor embedded data, which is used to store the register
+configuration used for capturing a given frame. The format is defined in the CCS
+specification.
+
+The bit depth of the CCS embedded data matches the pixel data bit depth
+configured on the sensor. The formats used and their corresponding generic
+formats are listed in the table below.
