The MIPI CSI-2 standard v2.0 specific VCX support feature is used to extend the maximum number of available virtual channels to 16. When this feature is enabled, the virtual channel is deduced by combining the 2-bit VC field (LSB) and the 2-bit VCX field (MSB) from the packet header.
Note: The IP reports ECC errors if the source is sending VC>3 and VCX Support is not selected. Hence, the source should not send VC>3 when VCX Support is not selected.
