I have two questions:
- on the card which integrates the LAN componant, there are also 2 buffers. I see 2 different power supplies. I assume 3.3V is needed, but which power supply is required for the second one? What is the role of those 2 buffers?
- NPWE is used on the PXA270 instead of NWE on the PXA255. Is it the new way of using it?
