I cannot determine from the datasheet how I should be driving this pin, should it come from a perpetual SSI clock? Or should it be driven off the tx clock off the ethernet phy chip?
Any information or a reference schematic on this clocking system would be very helpful. Thank you!
I think that pin is for doing timestamps of true AVB packets or generic Precision Time Protocol (gPTP). Are you even doing true AVB? Renesas does not generally provide AVB code, just driver code for doing normal Ethernet. Meaning, that pin is not used by default.
