Struct esp32h2::twai0::status::R

pub struct R(_);

Register STATUS reader

Implementations

impl R

pub fn receive_buffer(&self) -> RECEIVE_BUFFER_R

Bit 0 - 1: full, one or more complete messages are available in the RXFIFO. 0: empty, no message is available

pub fn overrun(&self) -> OVERRUN_R

Bit 1 - 1: overrun, a message was lost because there was not enough space for that message in the RXFIFO. 0: absent, no data overrun has occurred since the last clear data overrun command was given

pub fn transmit_buffer(&self) -> TRANSMIT_BUFFER_R

Bit 2 - 1: released, the CPU may write a message into the transmit buffer. 0: locked, the CPU cannot access the transmit buffer, a message is either waiting for transmission or is in the process of being transmitted

pub fn transmission_complete(&self) -> TRANSMISSION_COMPLETE_R

Bit 3 - 1: complete, last requested transmission has been successfully completed. 0: incomplete, previously requested transmission is not yet completed

pub fn receive(&self) -> RECEIVE_R

Bit 4 - 1: receive, the TWAI controller is receiving a message. 0: idle

pub fn transmit(&self) -> TRANSMIT_R

Bit 5 - 1: transmit, the TWAI controller is transmitting a message. 0: idle

pub fn err(&self) -> ERR_R

Bit 6 - 1: error, at least one of the error counters has reached or exceeded the CPU warning limit defined by the Error Warning Limit Register (EWLR). 0: ok, both error counters are below the warning limit

pub fn node_bus_off(&self) -> NODE_BUS_OFF_R

Bit 7 - 1: bus-off, the TWAI controller is not involved in bus activities. 0: bus-on, the TWAI controller is involved in bus activities

pub fn miss(&self) -> MISS_R

Bit 8 - 1: current message is destroyed because of FIFO overflow.

Methods from Deref<Target = R<STATUS_SPEC>>

pub fn bits(&self) -> REG::Ux

Reads raw bits from register.

Trait Implementations

impl Deref for R

type Target = R<STATUS_SPEC>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<R<STATUS_SPEC>> for R

fn from(reader: R<STATUS_SPEC>) -> Self

Converts to this type from the input type.
