* The following snippet is an example of how this module may be used within a typical
* application.
*
* \code
* // Initialize the Master SPI mode USART driver before first use, with 1Mbit baud
* SerialSPI_Init((USART_SPI_SCK_LEAD_RISING | SPI_SAMPLE_LEADING | SPI_ORDER_MSB_FIRST), 1000000);
- *
+ *
* // Send several bytes, ignoring the returned data
* SerialSPI_SendByte(0x01);
* SerialSPI_SendByte(0x02);
* SerialSPI_SendByte(0x03);
- *
+ *
* // Receive several bytes, sending a dummy 0x00 byte each time
* uint8_t Byte1 = SerialSPI_ReceiveByte();
* uint8_t Byte2 = SerialSPI_ReceiveByte();
* uint8_t Byte3 = SerialSPI_ReceiveByte();
- *
+ *
* // Send a byte, and store the received byte from the same transaction
* uint8_t ResponseByte = SerialSPI_TransferByte(0xDC);
* \endcode
