•Byte select access
•Signal multiplexing
• For 16-bit devices: the SMC provides NWR0 and NWR1 write signals for respectively byte0
The byte write access mode is used to connect two 8-bit devices as a 16-bit memory.
• For 32-bit devices: NWR0, NWR1, NWR2 and NWR3, are the write signals of byte0 (lower
The byte write option is illustrated on
In this mode, read/write operations can be enabled/disabled at a byte level. One byte select line
per byte of the data bus is provided. One NRD and one NWE signal control read and write.
• For 16-bit devices: the SMC provides NBS0 and NBS1 selection signals for respectively byte0
• For 32-bit devices: NBS0, NBS1, NBS2 and NBS3, are the selection signals of byte0 (lower
Figure 27-8 on page 490 shows how to connect two 16-bit devices on a 32-bit data bus in byte
select access mode, on NCS3.
Figure 27-7.
Depending on the MODE.BAT bit, only the write signals or the byte select signals are used. To
save I/Os at the external bus interface, control signals at the SMC interface are multiplexed.
