Reserved.
16
BIT1ERR
Bit 1 error. Indicates when an inconsistency occurs between the transmitted and the
received message in a bit. A read clears BIT1ERR.
0 No such occurrence
1 At least one bit sent as recessive is received as dominant
Note: This bit is not set by a transmitter in case of arbitration field or ACK slot, or in case
of a node sending a passive error flag that detects dominant bits.
17
BIT0ERR
Bit 0 error. Indicates when an inconsistency occurs between the transmitted and the
received message in a bit. A read clears BIT0ERR.
0 No such occurrence
1 At least one bit sent as dominant is received as recessive
18
ACKERR
Acknowledge error. Indicates that an acknowledge error has been detected by the
transmitter node; that is, a dominant bit has not been detected during the ACK SLOT. A
read clears ACKERR.
0 No such occurrence
1 An ACK error occurred since last read of this register
19
CRCERR
Cyclic redundancy code error. Indicates that a CRC error has been detected by the
receiver node; that is, the calculated CRC is different from the received. A read clears
CRCERR.
0 No such occurrence
1 A CRC error occurred since last read of this register.
20
FRMERR
Form error. Indicates that a form error has been detected by the receiver node; that is, a
fixed-form bit field contains at least one illegal bit. A read clears FRMERR.
0 No such occurrence
1 A form error occurred since last read of this register
21
STFERR
Stuffing error. Indicates that a stuffing error has been detected. A read clears STFERR.
0 No such occurrence.
1 A stuffing error occurred since last read of this register.
