1. Read the Channel Enable register to choose a free (disabled) channel.
2. Set up the chain of linked list items (otherwise known as block descriptors) in memory.
Write the control information in the LLI.CTLx register location of the block 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 destina-
b. Set up the transfer characteristics, such as:
– i. Transfer width for the source in the SRC_TR_WIDTH field.
– ii. Transfer width for the destination in the DST_TR_WIDTH field.
– iii. Source master layer in the SMS field where source resides.
– iv. Destination master layer in the DMS field where destination resides.
– v. Incrementing/decrementing or fixed address for source in SINC field.
– vi. Incrementing/decrementing or fixed address for destination DINC field.
