    I recently learned that there is an adress conflict between RTC and CAN2 adresses in the ST10F269. Can anybody tell more details about this problem or does anyone have an errata sheet describing this problem?

    Thanks

    Dear Neila !

    Thanks for the response. May I ask a few more questions:

    - Is there also a ChipSelect generated for RTC when CAN2 is accessed?

    - If a bus conflict occurs during read, which is the dominant bit level on XBus, Low or High ?

    - When switching the CAN2 temporarily OFF in the XPERCON register, is CAN2 being reset when switching it on again ? Is the register contents lost or damaged ?

    - Do you know wether and when this problem will be solved by STMicroelectronics ?

    Thanks and Regards
