Re: [68300] 68332 to flash, hardware connections

Technically, you should not tie OE to ground since this line should be pulled high during writes (programming).

The data lines should be connected in order.

The address lines depend on whether you are using the device in byte or word mode set by the #BYTE pin. The address lines should be in order as:

proc      flash
A1        A0
A2        A1
...       ...
A18       A17
If byte mode
A0        A-1
