Notes:
• Deep color mode can be monitored via deep_color_chng_raw, which indicates if the color depth of the processed HDMI stream
has changed.
• The ADV7850 can be configured to trigger an interrupt when deep_color_chng_raw changes from 0 to 1. In that configuration,
the interrupt status deep_color_chng_st indicates that deep_color_chng_raw has changed from 0 to 1. Refer to Section
additional information on the configuration of interrupts.
deep_color_chng_raw, IO, Address 0x83[7] (Read Only)
This readback indicates the status of deep color mode change interrupt signal. When set to 1, it indicates a change in the deep color
mode has been detected. Once set, this bit remains high until it is cleared via deep_color_chng_clr.

bg_deep_color_mode[1:0], Addr 68 (HDMI), Address 0xEA[3:2] (Read Only)
This readback provides the deep color status for the background HDMI port determined by bg_meas_port_sel[1:0]. The readback
provides the HDMI color depth and is updated when an update request is made via bg_meas_req. This measurement is valid only when
bg_param_lock is set to 1.
