svsp_enable_vom, Secondary VSP Map, Address 0xE610[5]
This bit is used to control the Video Output Module (VOM). If this bit is set to 1, the VOM is enabled to read video data from external
memory, process it and then output it.

If using the SVSP, the FFS must be enabled (using svsp_enable_ffs) so that the hardware knows the various conversions that must be
performed. The use of field/frame buffers in external memory is managed by the FFS which decides which frame buffer should be used by
the VIM to store input video data. The FFS also decides which frame buffer should be read back by the VOM. The SVSP utilizes a frame
repeat/drop mechanism to implement FRC, which is also managed by the FFS.
svsp_enable_ffs, Secondary VSP Map, Address 0xE610[7]
This bit is used to control the Field Frame Scheduler (FFS). If this bit is set to 1, the FFS is enabled and the VIM and VOM are
scheduled by the FFS, which means the Secondary VSP is in work mode. If this bit is set to 0, the Secondary VSP is in idle mode.

3.3.1.1. Autoconfiguration

Each block inside the VIM and the VOM can be automatically configured to decrease the configuration complexity. The
svsp_autocfg_input_vid[7:0]
59.94/23.97 Hz timings have the same VID as the corresponding 60/24 Hz timing in
svsp_autocfg_input_vid[7:0], Secondary VSP Map, Address 0xE660[7:0]
This register is used to set the input timing VIC. If this register is 0, SVSP will use values in registers of svsp_vin_h, svsp_vin_v and
svsp_vin_fr to set input video.
