D-Amax - D-A0
Amax indicates highest address bit for memory component:
a. Amax = A23 for NS256N, A22 for NS128N
b. Amax = A11 for 128 Mb DDR DRAM, A12 for 256-Mb DDR DRAM
For Flash, A0 – A15 is tied to DQ0 – DQ15.
For the NS512N, two NS-N devices are included. All signals are common to both except for CE#. F-CE# becomes F1-CE#, while the CE#
for the second flash is F2-CE#. This way, the two NS-N devices are separately accessed.
