13.3.2.1 Use Model 1: Accessing an 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 SmartFusion 2 MSS. In this example, the external SPI Flash is interfaced to MSS SPI_0. 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.
