    CANIT
    General Interrupt Flag
    (1)
    This status bit is the image of all the CAN controller interrupts sent to the
    interrupt controller.
    It can be used in the case of the polling method.
    6
    -
    Reserved
    The values read from this bit is indeterminate. Do not set this bit.
    5
    OVRTIM
    Overrun CAN Timer
    This status bit is set when the CAN timer switches 0xFFFF to 0x0000.
    If the bit ETIM in the IE1 register is set, an interrupt is generated.
    Clear this bit in order to reset the interrupt.
    4
    OVRBUF
    Overrun BUFFER
    0 - no interrupt.
    1 - IT turned on
    This bit is set when the buffer is full.
    Bit resetable by user.
    see Figure 46.
    3
    SERG
    Stuff Error General
    Detection of more than five consecutive bits with the same polarity.
    This flag can generate an interrupt. resetable by user.
    2
    CERG
    CRC Error General
    The receiver performs a CRC check on each destuffed received message
    from the start of frame up to the data field.
    If this checking does not match with the destuffed CRC field, a CRC error is
    set.
    This flag can generate an interrupt. resetable by user.
    1
    FERG
    Form Error General
    The form error results from one or more violations of the fixed form in the
    following bit fields:
    CRC delimiter
    acknowledgment delimiter
    end_of_frame
    This flag can generate an interrupt. resetable by user.
    0
    AERG
    Acknowledgment Error General
    No detection of the dominant bit in the acknowledge slot.
    This flag can generate an interrupt. resetable by user.
