Arria® 10 Hard Processor System Technical Reference Manual
17.3.1.1. Peripheral Request Interface Mapping
You can assign a peripheral request interface to any of the DMA channels. When a DMA channel thread executes DMAWFP, the value programmed in the peripheral [4:0] field specifies the peripheral associated with that DMA channel.
The DMAC supports 32 peripheral request handshakes. Each request handshake can receive up to four outstanding requests, and is assigned a specific peripheral device ID. The following table lists the peripheral device ID assignments.
