[En-Nut-Discussion] Address Bus

[Rodrigue]

Hello,

Board: Ethernut 1.3-Rev.G

The 16 address bits are formed by the 8 bits of the data bus (memorized by
the 74HC573D) and by the 8 bits of the adress bus. Why did you use this
method?

We could have sent the first 8 bits via the adress bus, then memorize them
via the 74HC573D, and to still return the 8 following bits via the adress
bus.

I suppose that would have been slower. Could you confirm or explain me why,
please?

In which file could I find the code responsible for the addressing of the
external memory of 32ko (K6X0808C1D), please?

TIA
Best Regards,
Rodrigue
