Notes:
• Deep color mode can be monitored via the deepcolor_mode_chng edge sensitive interrupt in the IO Map, which indicates if the
color depth of the processed stream has changed.
• The ADV8003 can be configured to trigger an interrupt when the deepcolor_mode_chng edge sensitive interrupt in the IO Map
changes from 0 to 1.

5.6. VIDEO FIFO

The ADV8003 contains a FIFO located after the TMDS decoding block (refer to
at 1X rate for non deep color modes (8-bits per channel), and 1.25X, 1.5X, or 2X for deep color modes (30, 36 and 48 bits respectively).
Data unpacking and data rate reduction must be performed on the incoming data to provide the ADV8003 digital core with the correct
data rate and data bit width. The video FIFO is used to pass data safely across the clock domains.
