• SADD: Source Address of DMA transfer
The starting System Bus source address is programmed by software before the DMA channel is enabled or by a LLI update
before the start of the DMA transfer. As the DMA transfer is in progress, this register is updated to reflect the source
address of the current System Bus transfer.
Updated after each source System Bus transfer. The SINC field in the CTLx register determines whether the address incre-
ments, decrements, or is left unchanged on every source System Bus transfer throughout the block transfer.
