Holds the start address of the external memory for
storing or fetching endpoint data. for control
endpoints, this field stores control OUT data packets
as well as SETUP transaction data packets. When
more than three SETUP packets are received back-to-
back, the SETUP data packet in the memory is
overwritten. This register is incremented on every
AHB transaction. The application can give only a
DWORD-aligned address. When Scatter/Gather
DMA mode is not enabled, the application programs
the start address value in this field. When Scatter/
Gather DMA mode is enabled, this field indicates the
base pointer for the descriptor list.
