Access Type:
• CANEN: CAN Controller Enable
0 = The CAN Controller is disabled.
1 = The CAN Controller is enabled.
• LPM: Disable/Enable Low Power Mode
w Power Mode.
1 = Enable Low Power M
CAN controller enters Low Power Mode once all pending messages have been transmitted.
• ABM: Disable/Enable Autobaud/Listen mode
0 = Disable Autobaud/listen mode.
1 = Enable Autobaud/listen mode.
• OVL: Disable/Enable Overload Frame
0 = No overload frame is generated.
1 = An overload frame is generated after each successful reception for mailboxes configured in Receive with/without over-
write Mode, Producer and Consumer.
• TEOF: Timestamp messages at each end of Frame
0 = The value of CAN_TIM is captured in the CAN_TIMESTP register at each Start Of Frame.
1 = The value of CAN_TIM is captured in the CAN_TIMESTP register at each End Of Frame.
• TTM: Disable/Enable Time Triggered Mode
0 = Time Triggered Mode is disabled.
1 = Time Triggered Mode is enabled.
• TIMFRZ: Enable Timer Freeze
0 = The internal timer continues to be incremented after it reached 0xFFFF.
1 = The internal timer stops incrementing after reaching 0xFFFF. It is restarted after a timer reset. See
