IEEE 1588 clock synchronization for multi-ports

I am using IMXRT1064 to implement IEEE 1588 function on two Ethernet ports simultaneously. So I need them to have a common reference timer. I saw in the manual that I can enable timer slave mode (ENETn_ATCR [SLAVE] = 1). By enabling slave mode (ENETn_ATCR[SLAVE] = 1), the timer is ignored and the current time is externally provided from one of the external modules.


How should I use it?

Thank you.
