Local system data bus
Primary data bus for memory. I/O and SDRAM.

Memory Address Bus
These signals provide the Memory or DRAM address, during a Memory or DRAM bus transaction. During
each word data, the address increments either in linear or sub-block ordering, depending on the transac-
tion type. The table below indicates how the memory write enable signals are used to address discreet
memory port width types.
mem_addr[22] Alternate function: reset_boot_mode[1].

mem_addr[18] Alternate function: modebit [8].
mem_addr[17] Alternate function: modebit [7].
mem_addr[16] Alternate function: sdram_addr[16].
mem_addr[15] Alternate function: sdram_addr[15].
mem_addr[14] Alternate function: sdram_addr[14].
mem_addr[13] Alternate function: sdram_addr[13].
mem_addr[11] Alternate function: sdram_addr[11].
mem_addr[10] Alternate function: sdram_addr[10].
mem_addr[9] Alternate function: sdram_addr[9].
mem_addr[8] Alternate function: sdram_addr[8].
mem_addr[7] Alternate function: sdram_addr[7].
mem_addr[6] Alternate function: sdram_addr[6].
mem_addr[5] Alternate function: sdram_addr[5].
mem_addr[4] Alternate function: sdram_addr[4].
mem_addr[3] Alternate function: sdram_addr[3].
mem_addr[2] Alternate function: sdram_addr[2].
mem_cs_n[5:0]

Low
Memory Chip Select Negated Recommend an external pull-up.
Signals that a Memory Bank is actively selected.
mem_oe_n
Output
H
High
Memory Output Enable Negated Recommend an external pull-up.
Signals that a Memory Bank can output its data lines onto the cpu_ad bus.
mem_we_n[3:0]
Output

Memory Write Enable Negated Bus
Signals which bytes are to be written during a memory transaction. Bits act as Byte Enable and
mem_addr[1:0] signals for 8-bit or 16-bit wide addressing.
