Field Documentation

◆ id

uint32_t MCAN_RxBufElement::id

Identifier

◆ rtr

uint32_t MCAN_RxBufElement::rtr

Remote Transmission Request 0 = Received frame is a data frame 1 = Received frame is a remote frame

◆ xtd

uint32_t MCAN_RxBufElement::xtd

Extended Identifier 0 = 11-bit standard identifier 1 = 29-bit extended identifier

◆ esi

uint32_t MCAN_RxBufElement::esi

Error State Indicator 0 = Transmitting node is error active 1 = Transmitting node is error passive

◆ rxts

uint32_t MCAN_RxBufElement::rxts

Rx Timestamp

◆ dlc

uint32_t MCAN_RxBufElement::dlc

Data Length Code 0-8 = CAN + CAN FD: received frame has 0-8 data bytes 9-15 = CAN: received frame has 8 data bytes 9-15 = CAN FD: received frame has 12/16/20/24/32/48/64 data bytes

◆ brs

uint32_t MCAN_RxBufElement::brs

Bit Rat Switching 0 = Frame received without bit rate switching 1 = Frame received with bit rate switching

◆ fdf

uint32_t MCAN_RxBufElement::fdf

FD Format 0 = Standard frame format 1 = CAN FD frame format (new DLC-coding and CRC)

◆ fidx

uint32_t MCAN_RxBufElement::fidx

Filter Index

◆ anmf

uint32_t MCAN_RxBufElement::anmf

Accepted Non-matching Frame 0 = Received frame matching filter index FIDX 1 = Received frame did not match any Rx filter element

◆ data

uint8_t MCAN_RxBufElement::data[MCAN_MAX_PAYLOAD_BYTES]

Data bytes. Only first dlc number of bytes are valid.
