NOE pin function in FSMC

NOE is the read signal line of the memory, N means low-level active, O means output, E means enable, and the
other line is NWE.
NWE is the write signal line of the memory, N means low-level active, W means write, E It means enable,

when writing memory, use NWE to output a low level, NOE keeps high level, when reading memory, use NOE to output a low level, NWE keeps high level, if you don’t understand anymore, you have to look at the classic 8086 bus Up.
