CAN FD Protocol Module
bit 3 STEF: Store in Transmit Event FIFO bit
(1)
1 = Saves transmitted messages in TEF
0 = Does not save transmitted messages in TEF
bit 2 SERRLOM: Transition to Listen Only Mode on System Error bit
(1)
1 = Transitions to Listen Only mode
0 = Transitions to Restricted Operation mode
bit 1 ESIGM: Transmit ESI in Gateway Mode bit
(1)
1 = ESI is transmitted as recessive when the ESI of message is high or CAN controller is error passive
0 = ESI reflects error status of the CAN controller
bit 0 RTXAT: Restrict Retransmission Attempts bit
(1)
1 = Restricted retransmission attempts, uses TXAT<1:0> (C1FIFOCONxH<6:5>)
0 = Unlimited number of retransmission attempts, TXAT<1:0> bits will be ignored
Register 3-1: C1CONH: CAN Control Register High (Continued)
Note 1: These bits can only be modified in Configuration mode (OPMOD<2:0> = 100 ).
