This flag is automatically cleared by reading CAN_SR register.

0: No bit error occurred during a previous transfer.

1: A bit error occurred during a previous transfer.

A bit error is set when the bit value monitored on the line is different from the bit value sent.

This flag is automatically cleared by reading CAN_SR register.

0: CAN receiver is not receiving a frame.

1: CAN receiver is receiving a frame.

Receiver busy. This status bit is set by hardware while CAN receiver is acquiring or monitoring a frame (remote, data, overload or 
error frame). It is automatically reset when CAN is not receiving.

0: CAN transmitter is not transmitting a frame.

1: CAN transmitter is transmitting a frame.

Transmitter busy. This status bit is set by hardware while CAN transmitter is generating a frame (remote, data, overload or error 
frame). It is automatically reset when CAN is not transmitting.

0: CAN transmitter is not transmitting an overload frame.

1: CAN transmitter is transmitting a overload frame.

It is automatically reset when the bus is not transmitting an overload frame.
