Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

DOEPDMA12 Fields

Bit Name Description Access Reset
31:0 DMAAddr 
 Holds the start address of the external memory for storing or fetching endpoint
data.
Note: 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.
