(CANRFPR) bit or the IRR1 from being set but simply prevents the interrupt signal from being
generated. If a message is received, it is unknown that the received message is for the previous
ID or for the new ID. Therefore, if a message is received a message during this period, it is
better to abandon this message, and this is the disadvantage of this method.
