Standard Read and Write Protocols
•Signal multiplexing
Figure 15-6.
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.
For 16-bit devices, bit A0 of address is unused. When byte select option is selected, NWR1 is
unused. When byte write option is selected, NBS0 to NBS1 are unused.
Table 15-3.
In the following sections, the byte access type is not considered. Byte select lines (NBS0 to
NBS1) always have the same timing as the address bus (A). NWE represents either the NWE
signal in byte select access type or one of the byte write lines (NWR0 to NWR1) in byte write
