flag
Bits 0 to 7 of the CAN receiver flag are as follows:
Bit Meaning Remarks
0 Not used
1 Overrun flag, set when data overrun
occurs 1: Data overrun detected
0: No data overrun
2 Bus off flag 1: CAN in bus off state
0: No bus off state
3 Transmitter error passive flag, set when
CAN enters error passive state due to
transmit error counter exceeding 127,
and bus off flag is clear 1: CAN in transmitter error
passive state
0: No transmitter error passive
state
4 Receiver error passive flag, set when
CAN enters error passive state due to
receive error counter exceeding 127,
and bus off flag is clear. 1: CAN in receiver error passive
state
0: No receiver error passive state
5 Transmitter warning flag 1: CAN in transmitter warning
state
0: No transmitter warning
6 Receiver warning flag 1: CAN in receiver warning state
0: No receiver warning state
7 Not used
Table 13-2: CAN Receiver Flag Bit 0…7
The CAN receive error counter (bits 8…15) reflects the status of the CAN receive
error counter. The CAN transmit error counter (bits 16…23) reflects the status of the
CAN transmit error counter.
The network status (bits 24…31) may be one of the following values:
5: Operational
127: Pre-operational
