CAN errors and error handling

8.5.5
Participant, bus off
If the error count value continues to be incremented, the participant is disconnected from the bus (bus
off) after exceeding a maximum count value.
To indicate this state the flag CANx_BUSOFF is set in the application program.
NOTE
The error CANx_BUSOFF is automatically handled and reset by the operating system. If the error is to
be handled or evaluated more precisely via the application program, the function
CANx_ERRORHANDLER (
→
page
) must be used. The error CANx_BUSOFF must then be reset
explicitly by the application program.
