7.11 Deep Color Mode Support

The ADV7604 supports HDMI streams with deep color modes of 24, 30, or 36 bits per sample. The
addition of a video FIFO (refer to Section 7.12) allows for the robust support of these modes.
The deep color mode information that the ADV7604 extracts from the general control packets can be
read back from DEEP_COLOR_MODE. It is possible to override the deep color mode that the
ADV7604 uses to unpack the video data encapsulated in the processed HDMI stream by configuring
the OVERRIDE_DEEP_COLOR_MODE
