Interrupt and status events.

All events can be cleared by Serial::clear_event or Serial::clear_events. Some events are also cleared on other conditions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TransmitDataRegisterEmtpy

Transmit data register empty / new data can be sent.

This event is set by hardware when the content of the TDR register has been transferred into the shift register. It is cleared by Serials serial::Write::write() implementation to the TDR register.

CtsInterrupt

CTS (Clear to Send) event.

This event is set by hardware when the CTS input toggles, if the CTSE bit is set.

TransmissionComplete

Transmission complete

This event is set by hardware if the transmission of a frame containing data is complete and if TXE is set. It is cleared by Serials serial::Write::write() implementaiton to the USART_TDR register.

ReceiveDataRegisterNotEmpty

Read data register not empty / new data has been received.

This event is set by hardware when the content of the RDR shift register has been transferred to the RDR register. It is cleared by Serials serial::Read::read() to the USART_RDR register.

OverrunError

Overrun Error detected.

This event is set by hardware when the data currently being received in the shift register is ready to be transferred into the RDR register while Event::ReceiveDataRegisterNotEmpty is set.

See Error::Overrun for a more detailed description.

Idle

Idle line state detected.

This event is set by hardware when an Idle Line is detected.

ParityError

Parity error detected.

This event is set by hardware when a parity error occurs in receiver mode.

Parity can be configured by using config::Parity to create a config::Config.

NoiseError

Noise error detected.

This event is set by hardware when noise is detected on a received frame.

FramingError

Framing error detected

This event is set by hardware when a de-synchronization, excessive noise or a break character is detected.

LinBreak

LIN break

This bit is set by hardware when the LIN break is detected.

CharacterMatch

The received character matched the configured character.

The matching character can be configured with Serial::match_character()

ReceiverTimeout

Nothing was received since the last received character for Serial::receiver_timeout() amount of time.

Note

Never set for UART peripheral, which does not have ReceiverTimeoutExt implemented.
