## ◆ ecc

uint8_t Vector::BLF::CanErrorFrameExt::ecc {}

error control code

Content of Philips SJA1000 Error Code Capture (ECC) register, or the Vector CAN-Core error register (see also flags).

SJA1000-ECC

See documentation of Philips SJA1000 CAN Controller.

Vector CAN-Core

Length of error frame, unused, may be 0.

## ◆ position

uint8_t Vector::BLF::CanErrorFrameExt::position {}

error position

Bit position of the error frame in the corrupted message.

## ◆ reservedCanErrorFrameExt1

uint8_t Vector::BLF::CanErrorFrameExt::reservedCanErrorFrameExt1 {}

reserved

## ◆ reservedCanErrorFrameExt2
