6.3.6 SPI Flash
To assist development of applications requiring external storage, a 4Mbit flash module is provided
(Adesto Tech. AT45DB041E-MHN2B-T). The flash uses an SPI interface with signals shared with the
expansion headers. When using multiple Chip Select (CS) signals, this allows the same SPI bus to be
used with both the Flash module and one or more SPI devices on an expansion shield. However, some
signals are also shared with the TSI user buttons.
