## Detailed Description

LIN_RCV_ERROR2.

This event may have a wide variety of causes. An external Master can cause a receive error event:

- by transmitting sync break that is too short,
- by not returning the correct value 0x55 in the sync field,
- by assigning an incorrect parity to the frame identifier. Other reasons:
- Slave transmitting an illegal character during a Bus Idle phase (e.g. because it did not finish transmission quickly enough and the checksum byte of the response was sent during the Bus Idle phase),
- Faulty (dominant) stop bit (i.e. framing error),
- LIN hardware receives a character that is different from the character sent during transmission
- LIN hardware only receives part of a frame, at the start of a measurement (in a correctly functioning system).

## Member Data Documentation

## ◆ earlyStopbitOffset

uint32_t Vector::BLF::LinReceiveError2::earlyStopbitOffset {}

Early stop bit offset for UART timestamps in ns.

Early stop bit offset in frame header for UART timestamps [in ns]

## ◆ earlyStopbitOffsetResponse

uint32_t Vector::BLF::LinReceiveError2::earlyStopbitOffsetResponse {}

Early stop bit offset in frame response for UART timestamps in ns.

Early stop bit offset in frame response for UART timestamps [in ns]

## ◆ exactHeaderBaudrate

double Vector::BLF::LinReceiveError2::exactHeaderBaudrate {}

Exact baudrate of the header in bit/sec.

Event's baudrate measured in header [in bits/sec]

## ◆ fsmId

uint8_t Vector::BLF::LinReceiveError2::fsmId {}

Slave Identifier in the Final State Machine (obsolete)

## ◆ fsmState

uint8_t Vector::BLF::LinReceiveError2::fsmState {}

State Identifier of a Slave in the Final State Machine (obsolete)

## ◆ hasDatabytes

uint8_t Vector::BLF::LinReceiveError2::hasDatabytes {}

Flag indicating whether at least one data byte value is valid

## ◆ isEtf

uint8_t Vector::BLF::LinReceiveError2::isEtf {}

ETF collision flag.

Flag indicating whether this frame is Event-Triggered one:

- 0: not ETF
- 1: ETF

## ◆ offendingByte

uint8_t Vector::BLF::LinReceiveError2::offendingByte {}

Byte value that resulted the protocol violation. Only valid for certain values of mStateReason

## ◆ reservedLinReceiveError

uint32_t Vector::BLF::LinReceiveError2::reservedLinReceiveError {}

reserved

## ◆ respBaudrate

uint32_t Vector::BLF::LinReceiveError2::respBaudrate {}

Response baudrate of the event in bit/sec.

Event's baudrate measured in response [in bits/sec]

## ◆ shortError

uint8_t Vector::BLF::LinReceiveError2::shortError {}

Specifies the detail level of the event. Following values are possible:

- 0: short
- 1: full Most members are not valid unless this member is 1

## ◆ stateReason

uint8_t Vector::BLF::LinReceiveError2::stateReason {}

The lower 4 bits indicate the LIN hard-ware state at the time the error has occurred, while the upper 4 bits indicate the reason of the error

Value for the state:

- 0: Bus idle
- 1: Waiting for SynchBreak
- 2: Waiting for SynchField
- 3: Waiting for frame ID
- 4-12: Waiting for data byte or checksum byte depending on the frame length. E.g. value 4 for FrameLength=0, value 12 for FrameLength=8
- 14: Consecutive event (i.e. event resulting from further data interpretation, after already notified error for first offending byte)
- 15: Not expected event (i.e. not WakeupRequest) during sleep mode. Occurs for LIN hardware in Master mode only

Values for the reason:

- 0: Timeout
- 1: Received an unexpected byte violating protocol. In this case, mOffendingByte member contains its value
- 2: Received a byte with framing error (with dominant stop bit). In this case, mOffendingByte member contains its value
- 3: Unexpected Break field
- 4: Unidentified error

## ◆ timeoutDuringDlcDetection

uint8_t Vector::BLF::LinReceiveError2::timeoutDuringDlcDetection {}

Flag indicating if the error is a result of an attempt to resolve frame length. Following values are possible:

- 0: False
- 1: True
