- * \code
- * // Initialize the Master SPI mode USART driver before first use, with 1Mbit baud
- * SerialSPI_Init((USART_SPI_SCK_LEAD_RISING | USART_SPI_SAMPLE_LEADING | USART_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);
