    Hi PY,

    Yes, if you do not need to use the RST (Reset) pin, then you can connect it ground.

    The VCCOUT requires a minimum capacitance of 10uF to ensure stability across all operating conditions regardless of whether you are not using the internal 5V LDO to source current to external circuitry because this same LDO is what supplies the internal CAN transceiver.

    Regards,
