Two memory regions are associated with the QSPI. The first memory region is dedicated to the configuration port. Using this memory region, all internal registers can be programmed and serial transfers made from the supported external SPI devices. The configuration port programming MMRs are available is 0x4820 0000 and the memory-mapped port regions start at 0x6000 0000 for memory region 1 and at 0x6200 0000 for memory region 2.
It is important to keep in mind that the configuration port provides an access to all the QSPI registers listed in the register summary. These are configuration registers and also four data registers. The configuration registers are used to configure typical SPI and serial flash memory settings and the four data registers are used for read and write operations. When communicating with an external SPI device (but not an SPI flash memory) the SPI_CORE module should be used and the data exchanged is available through these four data registers, which can be accessed only through the configuration port.
