RAM base address bit 8-15
These eight 8-bit registers (boundle to four 16-bit registers) defines the
most significant 16 bits
of each RAM banks' base (bottom) address. The "RAM base address" togather with the "RAM
size" (defined in ROMconf0) construct the whole address range of each RAM banks.
The base address of all four DRAM banks have no default value after power-on reset. It is software's
responsibility to well program these registers before access system DRAM.
