Struct InterruptStatus 

pub struct InterruptStatus {
    pub tx_complete: bool,
    pub tx_stopped: bool,
    pub tx_buf_unavailable: bool,
    pub tx_underflow: bool,
    pub rx_complete: bool,
    pub rx_stopped: bool,

    pub rx_overflow: bool,
    pub fatal_bus_error: bool,
    pub normal_summary: bool,
    pub abnormal_summary: bool,
}

Decoded DMA status flags.

Fields

tx_complete: bool

TX complete — a frame was transmitted successfully.

tx_stopped: bool

TX DMA stopped.

tx_buf_unavailable: bool

No TX descriptors available.

tx_underflow: bool

TX FIFO underflow.

rx_complete: bool

RX complete — a frame was received.

rx_stopped: bool

RX DMA stopped.

rx_buf_unavailable: bool

No RX descriptors available (DMA suspended).

rx_overflow: bool

RX FIFO overflow.

fatal_bus_error: bool

Fatal bus error — unrecoverable DMA error.

normal_summary: bool

Normal interrupt summary.

abnormal_summary: bool

Abnormal interrupt summary.

Implementations

impl InterruptStatus

pub fn from_raw(raw: u32) -> Self

Decode from a raw DMASTATUS register value.

pub fn to_raw(&self) -> u32

Encode back to a raw register value, retaining only the bits modeled by this struct.

Do not use this for write-1-to-clear of DMASTATUS — the struct does not represent every W1C flag (e.g. ERI, ETI, RWT, TJT, EBE[25:23]), so a roundtrip silently drops them. Use the raw DMASTATUS snapshot directly via crate::Emac::clear_interrupts_raw when clearing.

pub fn any(&self) -> bool

True if any non-summary bit is set.

pub fn has_error(&self) -> bool

True if any error flag is set.

Trait Implementations

impl Clone for InterruptStatus

fn clone(&self) -> InterruptStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for InterruptStatus

impl Debug for InterruptStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InterruptStatus

fn default() -> InterruptStatus

Returns the “default value” for a type.

impl Eq for InterruptStatus

impl Format for InterruptStatus

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for InterruptStatus

fn eq(&self, other: &InterruptStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
