bit TE0.31-30

Unimplemented: Read as ‘x’

bit TE0.29

SID11: In FD mode the standard ID can be extended to 12 bit using r1

bit TE0.28-11

EID<17:0>: Extended Identifier

bit TE0.10-0

SID<10:0>: Standard Identifier

bit TE1.31-9

SEQ<22:0>: Sequence to keep track of transmitted messages

bit TE1.8

ESI: Error Status Indicator

1 = Transmitting node is error passive

0 = Transmitting node is error active

bit TE1.7

FDF: FD Frame; distinguishes between CAN and CAN FD formats

bit TE1.6

BRS: Bit Rate Switch; selects if data bit rate is switched

bit TE1.5

RTR: Remote Transmission Request; not used in CAN FD

bit TE1.4

IDE: Identifier Extension Flag; distinguishes between base and extended format

bit TE1.3-0

DLC<3:0>: Data Length Code

bit TE2.31-0

TXMSGTS<31:0>: Transmit Message Time Stamp (1)

Note 1: TE2 (TXMSGTS) only exits in objects where CiTEFCON.TEFTSEN is set.
