Byte Write Access
Memory Connection for an 8-bit Data Bus
Memory Connection for a 16-bit Data Bus
A data bus width of 8 or 16 bits can be selected for each chip select. This option is controlled by
the field DBW in SMC_MODE (Mode Register) for the corresponding chip select.
Figure 25-4
connect a 512K x 16-bit memory on NCS2.
Each chip select with a 16-bit data bus can operate with one of two different types of write
access: byte write or byte select access. This is controlled by the BAT field of the SMC_MODE
register for the corresponding chip select.
Byte write access supports one byte write signal per byte of the data bus and a single read
signal.
Note that the SMC does not allow boot in Byte Write Access mode.
• For 16-bit devices: the SMC provides NWR0 and NWR1 write signals for respectively, byte0
(lower byte) and byte1 (upper byte) of a 16-bit bus. One single read signal (NRD) is provided.
Byte Write Access is used to connect 2 x 8-bit devices as a 16-bit memory.
