The main advantages of the SPI interface are truly its simplicity and the speed that can be one order of magnitude higher than that of the fastest I2C bus (even without taking into consideration the details of the protocol- specifi c overhead). Asynchronous serial interfaces The synchronization between transmitter and receiver is obtained by extracting timing information from the data stream itself. Start and stop bits are added to the data and precise formatting (with a fi xed baud rate) allow reliable data transfer. Parallel interfaces The Parallel Master Port (PMP) completes the list of basic communication interfaces of the PIC24. The PMP has the .
