DataFlash Service
Presentation
The DataFlash Service allows the Serial Peripheral Interface (SPI) to support several Serial
DataFlash and DataFlash Cards for reading, programming and erasing operations.
This service is based on SPI interrupts that are managed by a specific handler. It also uses the
corresponding PDC registers.
For more information on the commands available in the DataFlash Service, refer to the relevant
DataFlash documentation.

// Open communication pipe on the xmodem service
