## Member Function Documentation

## ◆ calculateObjectSize()

uint32_t Vector::BLF::Most150PktFragment::calculateObjectSize | ( |  | ) | const
| override virtual

Calculates the objectSize

Returns
  object size

Reimplemented from Vector::BLF::ObjectHeaderBase.

## ◆ read()

void Vector::BLF::Most150PktFragment::read | ( | AbstractFile & | is | ) |
| override virtual

Read the data of this object

Parameters

  is | input stream

Reimplemented from Vector::BLF::ObjectHeaderBase.

## ◆ write()

void Vector::BLF::Most150PktFragment::write | ( | AbstractFile & | os | ) |
| override virtual

Write the data of this object

Parameters

  os | output stream

Reimplemented from Vector::BLF::ObjectHeaderBase.

## Member Data Documentation

## ◆ ackNack

uint8_t Vector::BLF::Most150PktFragment::ackNack {}

acknowledge code

AckNack holds the transmit status of a control message (see Transmit Status Register of OS8104 for MOST25).

- Bit 0: Meaning:
  - 1: no response (NoResp) Restriction:
  - only for Dir = Tx or spy messages
- Bit 1: Meaning:
  - 1: valid receipt (Valid) Restriction:
  - only for Dir = Tx or spy messages
- Bit 2: Meaning:
  - 1: CRC Error (CRCError) Restriction:
  - only for Dir = Tx or spy messages
- Bit 3: Meaning:
  - 1: receive buffer full (RxBufFull) Restriction:
  - only for Dir = Tx or spy messages
- Bit 4: Meaning:
  - 1: acknowledged (Ack) Restriction:
  - only for Dir = Tx or spy messages (always set to 1 for Rx messages in node mode)
- Bit 5: Meaning:
  - 1: negative acknowledge (NAck) Restriction:
  - only for Dir = Tx or spy messages

## ◆ cAck

uint8_t Vector::BLF::Most150PktFragment::cAck {}

CRC acknowledge from the packet receiver(s) to the packet transmitter.

CRC acknowledge from the packet receiver(s) to the packet transmitter

- 0x00: No Response
- 0x01: CRC error
- 0x04: OK

## ◆ channel

uint16_t Vector::BLF::Most150PktFragment::channel {}

application channel

Application channel

## ◆ crc

uint32_t Vector::BLF::Most150PktFragment::crc {}

Cyclic Redundancy Check.

Cyclic Redundancy Check

## ◆ dataLen

uint32_t Vector::BLF::Most150PktFragment::dataLen {}

number of transmitted user data bytes

Number of transmitted user data bytes. These bytes were counted on bus.

Note: The number of bytes saved in this event is stored in mFirstDataLen.

## ◆ dataLenAnnounced

uint32_t Vector::BLF::Most150PktFragment::dataLenAnnounced {}

announced user data length at the start of the transmission

Announced user data length at start of transmission. In some cases (e.g. sending to an invalid target address, receive buffer full of target device) the transmission is terminated before all data bytes have been sent. Then the counted number of bytes on bus is less than the announced data length (dataLen < dataLenAnnonced). Due to rare and very specific bit errors (degrade of end termination byte) dataLen can also be greater than dataLenAnnonced.

## ◆ destAdr

uint32_t Vector::BLF::Most150PktFragment::destAdr {}

target address

Target address

## ◆ firstData

std::vector<uint8_t> Vector::BLF::Most150PktFragment::firstData {}

variable data

Variable data

## ◆ firstDataLen

uint32_t Vector::BLF::Most150PktFragment::firstDataLen {}

number of bytes in firstData

Number of bytes stored in firstData (1524 max).

Note: In order to limit the size of this event not all counted bytes on bus will be stored in the payload of the logging event.

## ◆ pAck

uint8_t Vector::BLF::Most150PktFragment::pAck {}

a preemptive acknowledge code

Pre-emptive acknowledge code

- 0x00: No Response
- 0x01: Buffer full
- 0x04: OK

## ◆ pIndex

uint8_t Vector::BLF::Most150PktFragment::pIndex {}

packet index, increments per message on MOST

Packet index, increments per message on MOST

## ◆ priority

uint8_t Vector::BLF::Most150PktFragment::priority {}

priority of the message

Priority (not used; write 0x00)

## ◆ reservedMost150PktFragment1

uint8_t Vector::BLF::Most150PktFragment::reservedMost150PktFragment1 {}

reserved

## ◆ reservedMost150PktFragment2

uint32_t Vector::BLF::Most150PktFragment::reservedMost150PktFragment2 {}

reserved

## ◆ sourceAdr

uint32_t Vector::BLF::Most150PktFragment::sourceAdr {}

source address

Source address

## ◆ validMask

uint32_t Vector::BLF::Most150PktFragment::validMask {}

bitfield indicating which members have valid data

If a bit in the mask is set, the corresponding data field has been seen on the bus.
