FLASH ROM write enable. This signal is used to write data into
the mrmory in a ROM bank (such as Flash ROM).
ROM output enable. This signal enables the selected ROM Bank
to drive the MD bus.
Memory controller Memory Address bus. For DRAM access,
MA[0:11] is the DRAM row address and the DRAM column
address. For ROM/FLASH ROM access, MA[0:11] is the higher
portion ROM space address bits in the first ROM address cycle,
and the lower portion ROM space address bits after the first ROM
address cycle. MA[0] is the most significant bit (msb).
Memory controller Data bus for both DRAM data and ROM space
data. Bit 0 is the most significant bit (msb).
