Enum PMAOVRR

pub enum PMAOVRR {
    NotOverrun = 0,
    Overrun = 1,
}

Packet memory area over / underrun This bit is set if the microcontroller has not been able to respond in time to an USB memory request. The USB peripheral handles this event in the following way: During reception an ACK handshake packet is not sent, during transmission a bit-stuff error is forced on the transmitted stream; in both cases the host retries the transaction. The PMAOVR interrupt should never occur during normal operations. Since the failed transaction is retried by the host, the application software has the chance to speed-up device operations during this interrupt handling, to be ready for the next transaction retry; however this does not happen during isochronous transfers (no isochronous transaction is anyway retried) leading to a loss of data in this case. This bit is read/write but only 0 can be written and writing 1 has no effect.

Value on reset: 0

Variants

NotOverrun = 0

0: Overrun is not occurred

Overrun = 1

1: Microcontroller has not been able to respond in time to an USB memory request

Trait Implementations

impl Clone for PMAOVRR

fn clone(&self) -> PMAOVRR

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PMAOVRR

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

Formats the value using the given formatter.

impl Format for PMAOVRR

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

Writes the defmt representation of self to fmt.

impl From<PMAOVRR> for bool

fn from(variant: PMAOVRR) -> Self

Converts to this type from the input type.

impl PartialEq for PMAOVRR

fn eq(&self, other: &PMAOVRR) -> 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.
