A.2. HPS Use of SDM QSPI Controller

The HPS has the capability to access serial NOR Flash connected to the SDM quad serial peripheral interface (SPI). The quad SPI flash controller supports standard SPI Flash devices as well as high-performance dual and quad SPI Flash devices.

Note: The data transfer speed when HPS is accessing the quad SPI controller is approximately one order of magnitude slower than when the SDM accesses it. You must consider whether this transfer speed meets your end application requirements.
