| 19 | The SPS (Smart Peripheral Switch) is a DMA engine. |
| 20 | It can move data in the following modes: |
| 21 | 1. Peripheral-to-Peripheral. |
| 22 | 2. Peripheral-to-Memory. |
| 23 | 3. Memory-to-Memory. |

| 30 | The BAM-DMA is used for Memory-to-Memory transfers. |
| 31 | The main use cases is RPC between processors. |
| 32 | The BAM-DMA hardware has 2 registers sets: |
| 33 | 1. A BAM HW like all the peripherals. |
| 34 | 2. A DMA channel configuration (i.e. channel priority). |
