Table 3-53. Tx Event FIFO Element Description (continued)
E1 Bits 31:24 MM[7:0]: Message Marker
Copied from Tx Buffer into Tx Event FIFO element for identification of Tx message status.
E1 Bit 23:22 ET[1:0]: Event Type
00 Reserved
01 Tx event
10 Transmission in spite of cancellation (always set for transmissions in DAR mode)
11 Reserved
E1 Bit 21 EDL: Extended Data Length
0 Standard frame format
1 CAN FD frame format (new DLC-coding and CRC)
E1 Bit 20 BRS: Bit Rate Switch
0 Frame transmitted without bit rate switching
1 Frame transmitted with bit rate switching
E1 Bits 19:16 DLC[3:0]: Data Length Code
0-8 CAN + CAN FD: Frame with 0-8 data bytes transmitted
9-15 CAN: Frame with 8 data bytes transmitted
9-15 CAN FD: frame with 12/16/20/24/32/48/64 data bytes transmitted
E1 Bits 15:0 TXTS[15:0]: Tx Timestamp
Timestamp Counter value captured on start of frame transmission. Resolution depending on
configuration of the Timestamp Counter Prescaler TSCC.TCP.
3.4.4 Standard Message ID Filter Element
Up to 128 filter elements can be configured for 11-bit standard IDs. When accessing a
Standard Message ID Filter element, its address is the Filter List Standard Start Address
SIDFC[FLSSA] plus the index of the filter element (0…127).
