This flag is automatically reset when above condition is not satisfied. Refer to
page 661
• BOFF: Bus Off Mode
0 = CAN controller is not in Bus Off Mode.
1 = CAN controller is in Bus Off Mode.
This flag is set depending on TEC counter value. A node is bus off when TEC counter is greater or equal to 256 (decimal).
This flag is automatically reset when above condition is not satisfied. Refer to
page 661
• SLEEP: CAN controller in Low power Mode
0 = CAN controller is not in low power mode.
1 = CAN controller is in low power mode.
This flag is automatically reset when Low power mode is disabled
• WAKEUP: CAN controller is not in Low power Mode
0 = CAN controller is in low power mode.
1 = CAN controller is not in low power mode.
When a WAKEUP event occurs, the CAN controller is synchronized with the bus activity. Messages can be transmitted or
received. The CAN controller clock must be available when a WAKEUP event occurs. This flag is automatically reset when
the CAN Controller enters Low Power mode.
• TOVF: Timer Overflow
0 = The timer has not rolled-over FFFFh to 0000h.
1 = The timer rolls-over FFFFh to 0000h.
This flag is automatically cleared by reading CAN_SR register.
• TSTP Timestamp
0 = No bus activity has been detected.
1 = A start of frame or an end of frame has been detected (according to the TEOF field in the CAN_MR register).
This flag is automatically cleared by reading the CAN_SR register.
• CERR: Mailbox CRC Error
0 = No CRC error occurred during a previous transfer.
1 = A CRC error occurred during a previous transfer.
A CRC error has been detected during last reception.
This flag is automatically cleared by reading CAN_SR register.
• SERR: Mailbox Stuffing Error
0 = No stuffing error occurred during a previous transfer.
1 = A stuffing error occurred during a previous transfer.
A form error results from the detection of more than five consecutive bit with the same polarity.
This flag is automatically cleared by reading CAN_SR register.
