Multi-buffer Transfer with Source Address Auto-reloaded and Linked List Destination Address (Row 6)
Figure 31-10. DMAC Transfer Flow for Source and Destination Address Auto-reloaded
1. Read the Channel Enable register to choose a free (disabled) channel.
2. Set up the chain of linked list items (otherwise known as buffer descriptors) in memory.
Write the control information in the LLI.DMAC_CTRLAx and DMAC_CTRLBx registers
location of the buffer descriptor for each LLI in memory for channel x. For example, in
the register you can program the following:
a. Set up the transfer type (memory or non-memory peripheral for source and desti-
b. Set up the transfer characteristics, such as:
– i. Transfer width for the source in the SRC_WIDTH field.
– ii. Transfer width for the destination in the DST_WIDTH field.
– iii. Source AHB master interface layer in the SIF field where source resides.
– iv. Destination AHB master interface layer in the DIF field where destination resides.
– v. Incrementing/decrementing or fixed address for source in SRC_INCR field.
– vi. Incrementing/decrementing or fixed address for destination DST_INCR field.
