ID18 Not Match Status
1 = 18-bit Identify pattern doesn’t match the received data. The status will be updated
0 = 18-bit Identify pattern matches the received data.
ID11 Not Match Status
1 = 11-bit Identify pattern doesn’t match the received data. The status will be updated
0 = 11-bit Identify pattern matches the received data.
Stuff Error
1 = A Stuff Error has to be detected at the bit time of the 6th consecutive equal bit level
0 = No stuff error.
Form Error
1 = A Form Error has to be detected when a fixed-form bit field contains one or more
0 = No fixed form error.
CRC Error
1 = The CRC sequence consists of the result of the CRC calculation by the transmitter.
0 = No CRC error.
Acknowledge Error
1 = An Acknowledge error has to be detected by a transmitter whenever it does not

illegal bits. The fixed-form includes the CRC delimiter, ACK delimiter, Error
Message Delimiter, Overflow Delimiter and EOF.
The receiver calculates the CRC in the same way as the transmitter. A CRC Error
has to be detected, if the calculated result is not the same as the received in the
CRC sequence.
