16.4.2.5.1. Internal DMA Controller Descriptors

The internal DMA controller uses these types of descriptor structures:
  • Dual‑buffer structure—The distance between two descriptors is determined by the skip length value written to the descriptor skip length field (dsl) of the bus mode register (bmod).

  • Chain structure—Each descriptor points to a unique buffer, and to the next descriptor in a linked list.
