非常感谢！另外请问一下，在手册22.4.1中提到"Aftersetup and subsequent transfer of message object from interface registers to message RAM, theacceptance filtering will be applied to it when the modified message object number is same or smaller thanthe previously found message object. This assures data consistency even when changing messageobjects; for example, while there is a pending CAN frame reception."这句话没太理解，为什么在正常工作期间，通过IFx继续修改message object，会和message object number优先级，以及acceptance filtering接收过滤有关系？
