3.3.3.3. Output Port

This section describes the configuration registers for the final block of the VOM of the SVSP. The main purpose of the output port is to
generate the output video timing and output the video data. For more details regarding the various register settings for the output port for
various common video formats, refer to
If the output configuration is to be set manually,
svsp_man_dp_timing_enable, Secondary VSP Map, Address 0xE663[7]
This bit is used to enable manually setting output timing.

svsp_dp_decount[10:0], Secondary VSP Map, Address 0xE632[7:0]; Address 0xE633[7:5]
This signal is used to set the DE duration of output timing. This register's value will be used while svsp_autocfg_output_vid is 0.

svsp_dp_hfrontporch[9:0], Secondary VSP Map, Address 0xE634[7:0]; Address 0xE635[7:6]
This signal is used to set the horizontal front porch duration of output timing. This register's value will be used while
svsp_autocfg_output_vid is 0.
