The Quad SPI (QSPI) module allows single, dual or quad read access to external SPI devices. This module provides a memory mapped register interface, which provides a direct interface to access data from external SPI devices and to simplify software requirements. It functions as a master only. There is one QSPI module in the device and it is primary intended for fast booting from quad-SPI flash memories.
