• AERR: Acknowledgment Error
0 = No acknowledgment error occurred during a previous transfer.
1 = An acknowledgment error occurred during a previous transfer.
An acknowledgment error is detected when no detection of the dominant bit in the acknowledge slot occurs.
This flag is automatically cleared by reading CAN_SR register.
• FERR: Form Error
0 = No form error occurred during a previous transfer
1 = A form error occurred during a previous transfer
A form error results from violations on one or more of the fixed form of the following bit fields:
This flag is automatically cleared by reading CAN_SR register.
• BERR: Bit Error
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.
• RBSY: Receiver busy
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, over-
load or error frame). It is automatically reset when CAN is not receiving.
• TBSY: Transmitter busy
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.
• OVLSY: Overload busy
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.
