5.6.5.1. Manager Interface

This interface allows the controller to act as a manager to perform DMA operations. The USB 3.1 controller uses the system bus interface to initiate data traffic with the system memory. These DMA transfers are requests initiated by the list processor (LSP) to the buffer management unit (BMU) which then initiates these DMA transfers through a native manager interface (GM). The DMA transfers are used to read/write descriptor data and read/write packet data.
