Hi,
In some condition ERRI Interrupt occours without any other error condition (CAN_ESR = 0). What is the meaning of this interrupt? Thank you. Alessandro

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.Regards
