This file contains the implementation of the interface functions for RGB2YCRCB driver. Refer to the header file <aclass="el"href="xrgb2ycrcb_8h.html">xrgb2ycrcb.h</a> for more detailed information.<p>
This function initializes the Rgb2YCrCb core. This function must be called prior to using the Rgb2YCrCb core. Initialization of the Rgb2YCrCb includes setting up the instance data and ensuring the hardware is in a quiescent state.<p>
