stm32n6 PPS in (ETH_PTP_AUX_TS)

[Noam_h]

Hello,

I need to sync the stm32n6 system timer to be used as PTP master. According to the Reference Manual there is a PPS input that can generate timestamp and interrupt: 

ETH_PTP_AUX_TS

But according to the RM it is not in all models, and I can't find which models it exists and how to map it to external IO.

Thanks,

Noam.

Unfortunately ETH_PTP_AUX_TS is not mapped on all products. On STM32N6, it's mapped with no internal signal only with timer output trigger or FDCAN..

Is it mapped to an external gpio?
