MCXN947: Is there a "1588_EVENT_IN" pin available?

is there a "1588_EVENT_IN" pin available?

I want to synchronize the internal 1588 timer to e.g. an external GPS PPS signal. Therefore, I need a input pin which capture the signal and store the 1588 counter.

In case of a RT1170, I can found e.g. “ENET_1588_EVENT0_IN” pin. But I can not found such a pin for the N947.

Best regards,

Hello @michael_fischer ,

Thanks for your port.

No, the MCXN947 does not provide an external 1588 event input pin.

Hope it helps.

Hello @Celeste_Liu

It's a pity that such a pin is not available. I thought I had just overlooked it. Then I have to think of something else here for synchronization to a GPS PPS signal.

Plan B is to add both signals to inputs from the CTIMER and thus determine the time difference.
