DDR2 Interface

The ADV8003 uses DDR2 memory to enable the de-interlacer, scaler and OSD features. The DDR2 interface on ADV8003 is designed to
meet the JESD79-2F standard.

2.2.5.1. DDR2 Configuration

The controls described in this section are used to configure the ADV8003 DDR2 memory interface.
The first three bits configure the DDR2 memory interface for the external memory configuration. The
size of the attached memory or memories. For example, if using 256 Mbit memory,
Mbit memory, sdram_size[3:0]
The word_size[3:0] and burst_length[2:0]
connected to the ADV8003. If there is a single DDR2 memory,
and bursts of 8. If there are dual DDR2 memories,
