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. |
