If you use /MSTRB signal for Flash /CE, then A16 and A17 will be controlled correctly -- and automatically -- by the C5416:

32k Page /MSTRB A16, A17
-------- ------ --------
0, onchip not active NA
1, onchip NA NA
2, onchip NA NA
3, onchip NA NA
4, offchip active 00
5, offchip active 01
6, offchip active 10
7, offchip active 11

It is correct to leave A15 as NC.
