- *
- *  \section Sec_SPI_AVR8_ModDescription Module Description
- *  Driver for the hardware SPI port available on most 8-bit AVR microcontroller models. This
- *  module provides an easy to use driver for the setup and transfer of data over the
- *  AVR's SPI port.
- *
- *  \note This file should not be included directly. It is automatically included as needed by the SPI driver
- *        dispatch header located in LUFA/Drivers/Peripheral/SPI.h.
- *
- *  \section Sec_SPI_AVR8_ExampleUsage Example Usage
- *  The following snippet is an example of how this module may be used within a typical
- *  application.
- *
- *  \code
- *      // Initialize the SPI driver before first use
- *      SPI_Init(SPI_SPEED_FCPU_DIV_2 | SPI_ORDER_MSB_FIRST | SPI_SCK_LEAD_FALLING |
- *               SPI_SAMPLE_TRAILING | SPI_MODE_MASTER);
- *
- *      // Send several bytes, ignoring the returned data
- *      SPI_SendByte(0x01);
- *      SPI_SendByte(0x02);
- *      SPI_SendByte(0x03);
- *
- *      // Receive several bytes, sending a dummy 0x00 byte each time
- *      uint8_t Byte1 = SPI_ReceiveByte();
- *      uint8_t Byte2 = SPI_ReceiveByte();
- *      uint8_t Byte3 = SPI_ReceiveByte();
- *
- *      // Send a byte, and store the received byte from the same transaction
- *      uint8_t ResponseByte = SPI_TransferByte(0xDC);
- *  \endcode
