    Hello,

    - ERRI: Error interruptThis bit is set by hardware when a bit of the CAN_ESR has been set on error detection andthe corresponding interrupt in the CAN_IER is enabled. Setting this bit generates a statuschange interrupt if the ERRIE bit in the CAN_IER register is set.This bit is cleared by software.

    - ERRIE: Error interrupt enable

      0: No interrupt will be generated when an error condition is pending in the CAN_ESR.

     1: An interrupt will be generation when an error condition is pending in the CAN_ESR.

    You have to refer to the reference manual for more details on this topic.
