+ * @defgroup AT91SAM7_SPI AT91SAM7 SPI Support

+ * @details The SPI driver supports the AT91SAM7 SPI peripherals using DMA

+ *          channels for maximum performance.

+ *

+ * @section at91sam7_spi_1 Supported HW resources

+ * - SPI1.

+ * - SPI2.

+ * .

+ * @section at91sam7_spi_2 AT91SAM7 SPI driver implementation features

+ * - Clock stop for reduced power usage when the driver is in stop state.

+ * - Each SPI can be independently enabled and programmed. Unused

+ *   peripherals are left in low power mode.

+ * - Programmable interrupt priority levels for each SPI.

+ * - DMA is used for receiving and transmitting.

+ * .

+ * @ingroup AT91SAM7
