impl Isr

pub const fn rxbr(&self) -> bool

pub const fn rxovr(&self) -> bool

Rx-Overrun RXOVR is set by hardware if RXBR is not yet cleared at the time a new byte is received on the CEC line and stored into RXD.

pub const fn bre(&self) -> bool

Rx-Bit Rising Error BRE is set by hardware in case a Data-Bit waveform is detected with Bit Rising Error. BRE is set either at the time the misplaced rising edge occurs, or at the end of the maximum BRE tolerance allowed by RXTOL, in case rising edge is still longing. BRE stops message reception if BRESTP=1. BRE generates an Error-Bit on the CEC line if BREGEN=1. BRE is cleared by software write at 1.

pub fn set_bre(&mut self, val: bool)

Rx-Bit Rising Error BRE is set by hardware in case a Data-Bit waveform is detected with Bit Rising Error.

BRE stops message reception if BRESTP=1. BRE generates an Error-Bit on the CEC line if BREGEN=1. BRE is cleared by software write at 1.

pub const fn sbpe(&self) -> bool

Rx-Short Bit Period Error SBPE is set by hardware in case a Data-Bit waveform is detected with Short Bit Period Error. SBPE is set at the time the anticipated falling edge occurs. SBPE generates an Error-Bit on the CEC line. SBPE is cleared by software write at 1.

pub fn set_sbpe(&mut self, val: bool)

pub const fn lbpe(&self) -> bool

Rx-Long Bit Period Error LBPE is set by hardware in case a Data-Bit waveform is detected with Long Bit Period Error. LBPE is set at the end of the maximum bit-extension tolerance allowed by RXTOL, in case falling edge is still longing. LBPE always stops reception of the CEC message. LBPE generates an Error-Bit on the CEC line if LBPEGEN=1. In case of broadcast, Error-Bit is generated even in case of LBPEGEN=0. LBPE is cleared by software write at 1.

pub fn set_lbpe(&mut self, val: bool)

Rx-Long Bit Period Error LBPE is set by hardware in case a Data-Bit waveform is detected with Long Bit Period Error. LBPE is set at the end of the maximum bit-extension tolerance allowed by RXTOL, in case falling edge is still longing. LBPE always stops reception of the CEC message. LBPE generates an Error-Bit on the CEC line if LBPEGEN=1. In case of broadcast, Error-Bit is generated even in case of LBPEGEN=0. LBPE is cleared by software write at 1.

pub const fn rxacke(&self) -> bool

Rx-Missing Acknowledge In receive mode, RXACKE is set by hardware to inform application that no acknowledge was seen on the CEC line. RXACKE applies only for broadcast messages and in listen mode also for not directly addressed messages (destination address not enabled in OAR). RXACKE aborts message reception. RXACKE is cleared by software write at 1.

pub fn set_rxacke(&mut self, val: bool)

Rx-Missing Acknowledge In receive mode, RXACKE is set by hardware to inform application that no acknowledge was seen on the CEC line. RXACKE applies only for broadcast messages and in listen mode also for not directly addressed messages (destination address not enabled in OAR). RXACKE aborts message reception. RXACKE is cleared by software write at 1.

pub const fn arblst(&self) -> bool

Arbitration Lost ARBLST is set by hardware to inform application that CEC device is switching to reception due to arbitration lost event following the TXSOM command. ARBLST can be due either to a contending CEC device starting earlier or starting at the same time but with higher HEADER priority. After ARBLST assertion TXSOM bit keeps pending for next transmission attempt. ARBLST is cleared by software write at 1.

pub fn set_arblst(&mut self, val: bool)

Arbitration Lost ARBLST is set by hardware to inform application that CEC device is switching to reception due to arbitration lost event following the TXSOM command. ARBLST can be due either to a contending CEC device starting earlier or starting at the same time but with higher HEADER priority.

pub const fn txbr(&self) -> bool

Tx-Byte Request TXBR is set by hardware to inform application that the next transmission data has to be written to TXDR. TXBR is set when the 4th bit of currently transmitted byte is sent.

Trait Implementations

impl Clone for Isr

fn clone(&self) -> Isr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Isr

fn default() -> Isr

Returns the “default value” for a type.

impl PartialEq for Isr

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