As stated there, CAN requires a clock accuracy of 1.58% or your CAN node is non-compliant. I would recommend to use <1% however, which usually means external quartz. Some MCUs have good enough internal RC oscillators, your does not. You must use a crystal oscillator for CAN if sticking with this MCU.
