FD506 has variable interface data input including 8/9/16/18 bits and data depth (666 or 565),
therefore before writing into memory it needs to be latched and normalized. The aim of this block
is to normalize the input data from variable MPU interface and save them to memory in regular
way. Following diagram shows the data flow in this block.
The size of SRAM of FD506 is 640x240x3x6 bits. It can be configured into 6 parts and each part
has 6 bits width.
