Trait implemented by all DMA channels

Required Methods§

Source

fn select_peripheral(&mut self, index: DmaMuxIndex)

Connects the DMAMUX channel to the peripheral corresponding to index

Source

fn event_occurred(&self, event: Event) -> bool

Is the interrupt flag for the given event set?

Source

fn clear_event(&mut self, event: Event)

Clear the interrupt flag for the given event.

Passing Event::Any clears all interrupt flags.

Note that the the global interrupt flag is not automatically cleared even when all other flags are cleared. The only way to clear it is to call this method with Event::Any.
