From this datasheet for the part:http://pdf1.alldatasheet.com/datasheet-pdf/view/47677/WINBOND/W55F10.html
I'd have to say, I don't know!
I would guess you could connect it to any 6 pins you wanted and then bit-bang out the transfers, possibly 32 bits at a time, with the up to 128K of data ( 1 Mbit for the W55F10) coming in from a PC.
The different Modes are not explained at all. Perhaps more data is available on the datasheets for these other parts:
"The W55FXX is a serial input/output flash EEPROM series that is typically used as the memory cell
of a W51300 (voice recorder controller) or the ROM code emulator for the PowerSpeechTM series."
Try searching the Playground for a Library for this part, maybe you'll get lucky. If not, you need to do some more research more first.
