Progressive to Interlaced Converter

The main progressive to interlaced (PtoI) converter can be connected to many blocks, for example, Video TTL input channel, EXOSD
TTL input channel, PVSP, and so on. The block can be used for video conversion, for example, conversion of 1080p to 1080i. It drops the
progressive video odd or even lines based on the field signal of the output interlaced video. It can only support 480p, 576p, and 1080p
input. The associated interlaced timing signals can be generated in the independent PtoI hardware block.
By enabling m_p2i_drop_line_as_pvsp_flag, the PtoI module can drop interpolated lines to get optimal output performance.
The PtoI hardware can be enabled using m_p2i_enable.
m_p2i_enable, Secondary VSP Map, Address 0xE649[4]
This bit is used to enable the PtoI in VSP_top.

m_p2i_drop_line_as_pvsp_flag, Secondary VSP Map, Address 0xE65B[7]
This bit is used to select an interlaced mode in game mode. If PVSP works in game mode and PVSP's input is interlaced, this bit should
be set to 1 for P2I to drop interpolated lines. Otherwise, this bit should be set to 0.
