## Member Data Documentation

## ◆ ackNack

uint8_t Vector::BLF::MostEthernetPkt::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::MostEthernetPkt::cAck {}

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

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

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

## ◆ channel

uint16_t Vector::BLF::MostEthernetPkt::channel {}

application channel

Application channel

## ◆ crc

uint32_t Vector::BLF::MostEthernetPkt::crc {}

Cyclic Redundancy Check.

48 bit target address

48 bit target address

## ◆ dir

uint8_t Vector::BLF::MostEthernetPkt::dir {}

direction: 0: Rx; 1: Tx; 2: TxRequest

Direction of message events:

- 0: Rx (received)
- 1: Tx (transmit receipt)
- 2: Tx Request (transmit request)

## ◆ pAck

uint8_t Vector::BLF::MostEthernetPkt::pAck {}

a preemptive acknowledge code

Pre-emptive acknowledge code (spy only)

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

## ◆ pktData

std::vector<uint8_t> Vector::BLF::MostEthernetPkt::pktData {}

variable data

Variable data

## ◆ pktDataLength

uint32_t Vector::BLF::MostEthernetPkt::pktDataLength {}

length of variable data in bytes (1506 max)

Length of variable data in bytes (1506 max)

## ◆ reservedMostEthernetPkt1

uint8_t Vector::BLF::MostEthernetPkt::reservedMostEthernetPkt1 {}

uint64_t Vector::BLF::MostEthernetPkt::sourceMacAdr {}

48 bit source address

48 bit source address

## ◆ state

uint8_t Vector::BLF::MostEthernetPkt::state {}

transmission status

Transmission states of MOST50/150 messages and packets.

- Bit 0: Meaning:
  - 0: bus inactive
  - 1: bus active Restriction:
  - only for Dir = Rx or mTransferType = Spy
- Bit 4: Meaning:
  - 1: acknowledged (Ack) Restriction
  - only for mTransferType = Node and Dir = Tx (always set to 1 for Rx messages in node mode)
- Bit 5: Meaning:
  - 1: not acknowledged (NAck) Restriction:
  - only for Dir = Tx
- Bit 6: Meaning: Send result:
  - 0: Transmission error (TxF)
  - 1: OK Restriction:
  - only for Dir = Tx
  - only for mTransferType = Node

## ◆ transferType

uint8_t Vector::BLF::MostEthernetPkt::transferType {}

Tranfer Type.

Message-like events can either be recorded through the MOST transceiver chip or through a separate network spy.

- 1: Node MOST transceiver reported the message (either due to a successful reception or as acknowledgment for a transmit request).
- 2: Spy Message was reported by the network spy. The Spy sees all messages independently of the desti-nation address.
