The address offset for each channel is: [x *0x58]

• SADD: Source Address of DMA transfer
The starting AMBA 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 AMBA transfer.
Updated after each source AMBA transfer. The SINC field in the DMAC_CTLx register determines whether the address
increments, decrements, or is left unchanged on every source AMBA transfer throughout the block transfer.
