Field
Description
31–16
Reserved, must be cleared.
15
BIT1ERR
Bit1 error. Indicates inconsistency between the transmitted and received bit in a message.
0 No transmit bit error
1 At least one bit sent as recessive was received as dominant
Note: The transmit bit error field is not modified during the arbitration field or the ACK slot bit time of a message,
or by a transmitter that detects dominant bits while sending a passive error frame.
14
BIT0ERR
Bit0 error. Indicates inconsistency between the transmitted and received bit in a message.
0 No transmit bit error
1 At least one bit sent as dominant was received as recessive
13
ACKERR
Acknowledge error. Indicates whether an acknowledgment has been correctly received for a transmitted message.
0 No ACK error was detected since the last read of this register.
1 An ACK error was detected since the last read of this register.
12
CRCERR
Cyclic redundancy check error. Indicates whether or not a CRC error has been detected by the receiver.
0 No CRC error was detected since the last read of this register.
1 A CRC error was detected since the last read of this register.
11
FRMERR
Message form error. Indicates that a form error has been detected by the receiver node, i.e. a fixed-form bit field
contains at least one illegal bit.
0 No form error was detected since the last read of this register.
1 A form error was detected since the last read of this register.
10
STFERR
Bit stuff error.
0 No bit stuffing error was detected since the last read of this register.
1 A bit stuffing error was detected since the last read of this register.

IDLE
Idle status. Indicates when there is activity on the CAN bus.
0 The CAN bus is not idle.
1 The CAN bus is idle.
