Further Discussion of IEEE 1588v2 and LS1021A

This discussion is regarding my further questions of my last topic "IEEE 1588v2 and LS1021A".

I got the answer: all Ethernet controllers are supported by IEEE 1588v2 on LS1021A. When I look into the pin assignment of LS1021A, I find that for the 1588v2 hardware signals on the LS1021A share pins with EC3 signals. For example,  EC3_RXD0 and TSEC_1588_TRIG_IN2 share the same pin of LS1021A. So when the EC3 is operating in RGMII mode, how could 1588v2 work with these shared pins?
