Figure 12 shows how to connect a 16-bit device with byte and half-word access (e.g. 16-
bit SRAM) on NCS2.
Figure 12. Connection for a 16-bit Data Bus with Byte and Half-word Access
Figure 13 shows how to connect a 16-bit device without byte access (e.g. Flash) on
NCS2.

The signal A0/NLB is used as NLB and enables the lower byte for both read and
write operations.
The signal NWR1/NUB is used as NUB and enables the upper byte for both read
and write operations.
The signal NWR0/NWE is used as NWE and enables writing for byte or half word.
The signal NRD/NOE is used as NOE and enables reading for byte or half word.
