4.3.6 Serial Peripheral Interface Controller (SPI)
The SAMA5D3 series processor provides two high-speed Serial Peripheral Interface (SPI) controllers. One port is used
to interface with the on-board serial DataFlash. Note that the on-board serial DataFlash is enabled through a jumper: JP1
on Embest modules, J1 on Ronetix modules. The jumper must be in place access (and boot) the serial DataFlash.
