vid_av_codes_rep_man_en, IO Map, Address 0x1B4B[1]
This bit is used to control the enable for AV source codes. AV_codes_rep_man is used instead of the auto based on the input video
format.

vid_av_codes_rep_man, IO Map, Address 0x1B4B[0]
This bit is used to specify if the AV_codes are replicated or not.
Codes replicated (4:4:4) = FF,FF,FF,00,00,00,00,00, 00,AV,AV,AV.
Codes not replicated = FF,00,00,AV.

The updither feature in the ADV8003 can be used to randomize quantization errors, preventing large scale patterns such as color banding
in images. Refer to Section
The updither block on the video TTL input channel can be controlled via the
default, the manual bypass is disabled which means that the updither block cannot be bypassed. The updither block configuration is
outlined in Section 2.2.3. The updither settings are shared for all channels (primary, secondary and RX).
vid_ud_bypass_man_en, IO Map, Address 0x1B4A[2]
This bit is used to enable the manual bypass for the up dither. Setting this bit enables the bypass to be used.
