Address Bus: The 22-bit address bus (including ADDR[21:20] above) covers 4M
word memory space shared by ROM/SRAM/FLASH, SDRAM, and external I/O
banks. During the SDRAM cycles, the internal address bus is used to generate RAS
and CAS addresses for the SDRAM. The number of column address bits in the
SDRAM banks can be programmed from 8 to 11 bits via the SDRAM control
registers. ADDR[12:0] are the SDRAM address, and ADDR[21:20] are the SDRAM
bank address. During other cycles, the ADDR[21:0] is the byte address of the data
transfer.
Note: The address pinout non-sequential by design. It is optimized for board level
connections to SDRAM.
For SDRAM and ROM/SRAM/Flash, connect ADDR[0] to A0 on the memory,
ADDR[1] to A1 on the memory, and so forth. Address bit mapping for 8-bit, 16-bit,
32-bit access.
For external I/O devices, the system designer must connect address lines
conventionally for 8-bit, 16-bit, and 32-bit access.

O = Output.
NC = No connect.
