}

Type-level enum representing a Serial Communication Interface (SERCOM)

Required Associated Constants

const NUM: usize

SERCOM number

const DMA_RX_TRIGGER: TriggerSource

RX Trigger source for DMA transactions

const DMA_TX_TRIGGER: TriggerSource

TX trigger source for DMA transactions

Required Associated Types

type Interrupt: InterruptSource

Required Methods

fn enable_apb_clock(&mut self, ctrl: &ApbClkCtrl)

Enable the corresponding APB clock

fn reg_block(peripherals: &mut Peripherals) -> &RegisterBlock

Get a reference to the sercom from a Peripherals block

Provided Methods

fn rx_waker() -> &'static AtomicWaker

Get a reference to this Sercom’s associated RX Waker

fn tx_waker() -> &'static AtomicWaker

Get a reference to this Sercom’s associated TX Waker

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
