SJA1000_ERROR_FIFOOVERRUN: an overrun of the CANbus controller’s
internal receiver FIFO occurred,
SJA1000_ERROR_BUFFEROVERRUN: an overrun of the read ring buffer
maintained by the firmware occurred,
SJA1000_ERROR_BUSOFF: a bus-off event on the CANbus occurred.
LastErrorCapture:
This reflects the contents of the CANbus controller’s Error Capture Register (ECC) at
the moment when a bus error was detected. This can give additional information
about the type and location of the error. See the data sheet of the SJA1000 CANbus
controller for a description of the ECC.
LastArbitLostCapture:
This reflects the contents of the CANbus controller’s Arbitration Lost Capture Register
(ALC) at the moment when an arbitration lost was detected. This can give additional
information about the bit position where the lost occurred. See the data sheet of the
SJA1000 CANbus controller for a description of the ALC.
pad:
For alignment purposes.
AmountInInQueue:
The number of bytes that reside currently in the port’s read ring buffer.
AmountInOutQueue:
The number of bytes that reside currently in the port’s write buffer.
