Address Signal Mapping (32-bit Data Bus)
bank selection in memory with a two-bank configuration. [B1:B0] are used in the bank selection
in memory with a four-bank configuration. Bits with the description "L/H" output High when
performing auto-precharging, or output Low when not performing auto-precharging.
