14.3.2.1 Use Model 1: Accessing the External SPI Flash Using MSS SPI_0
The external SPI flash can be interfaced to either the MSS SPI_0 or SPI_1 peripherals of the
SmartFusion2 MSS. In this example, the external SPI flash is interfaced to MSS SPI_0. The MSS SPI_0
is configured as a master with the slave select line connected to the chip select of the external SPI Flash.
The following figure shows interfacing the external SPI flash to MSS SPI_0.
