7.40 COLOR SPACE INFORMATION SENT TO THE CP SECTION

The HDMI section sends information regarding the color space of the video it outputs to the CP sections. This color space information is
derived from the DVI/HDMI status of the input stream the HDMI section processes and from the AVI InfoFrame that the HDMI section
decodes from the input stream. The color space information sent by the HDMI section to the CP section can be read via
hdmi_colorspace[3:0].
hdmi_colorspace[3:0], Addr 68 (HDMI), Address 0x53[3:0] (Read Only)
This readback displays the HDMI input color space decoded from the AVI InfoFrame.
