25.3.5 Events

The USART can generate the following events:

Generator NameDescriptionEvent TypeGenerating Clock DomainLength of Event
PeripheralEvent
USARTnXCKThe clock signal in Synchronous Host mode and SPI Host modeLevelCLK_PEROne XCK period

The conditions for generating an event are identical to those that will raise the corresponding flag in the Interrupt Flags (USARTn.INTFLAGS) register.

The USART has one event user for detecting and acting upon input events. The table below describes the event user and the associated functionality.
