Hi,
Can anyone please help me with DMA info for the LPC13Uxx devices?

The documentation contains this or similar remarks throughout.
Remark: The memory address set in this field should be accessible by USB DMA controller. Also this
value should be aligned on 4 byte boundary.

I have unsuccessfully searched to find which memory items satisfy these criteria.
