Name:
Access Type:
• MBx: Mailbox x Event
0 = No event occurred on Mailbox x.
1 = An event occurred on Mailbox x.
An event corresponds to MRDY, MABT fields in the CAN_MSRx register.
• ERRA: Error Active Mode
0 = CAN controller is not in Error Active Mode.
1 = CAN controller is in Error Active Mode.
This flag is set depending on TEC and REC counter values. It is set when node is neither in Error Passive Mode nor in Bus
Off Mode.
This flag is automatically reset when above condition is not satisfied. Refer to
page 561
• WARN: Warning Limit
0 = CAN controller Warning Limit is not reached.
1 = CAN controller Warning Limit is reached.
This flag is set depending on TEC and REC counter values. It is set when at least one of the counter values exceeds 96.
This flag is automatically reset when above condition is not satisfied. Refer to
page 561
• ERRP: Error Passive Mode
0 = CAN controller is not in Error Passive Mode.
1 = CAN controller is in Error Passive Mode.
This flag is set depending on TEC and REC counters values.
A node is error passive when TEC counter is greater or equal to 128 (decimal) or when the REC counter is greater or equal
to 128 (decimal).
This flag is automatically reset when above condition is not satisfied. Refer to
page 561
