EFM32 USART - Synchronous mode(SPI)
■The EFM32 Universal Synchronous Asynchronous serial Receiver and Transmitter (USART) is a very flexible serial communication module. It operates in either synchronous or asynchronous mode.
■In synchronous mode, a separate clock signal is transmitted with the data. This clock signal is generated by the bus master, and both the master and slave sample and transmit data according to this clock.Both master and slave modes are supported by the USART. The synchronous communication mode is compatible with the Serial Peripheral Interface Bus (SPI) standard.
■In asynchronous mode, no separate clock signal is transmitted with the data on the bus. The USART receiver thus has to determine when to sample the data on the bus. To make this possible, additional synchronization bits are added to the data when operating in asynchronous mode, resulting in a slight overhead
