GPIOs for IEEE1588

Question asked by KenYe Employee on Jun 4, 2012

Hello, can anyone tell me how is the detail difinition of the following GPIOs and how to use them?

It looks such pins are related to the IEEE1588... but I can't find any detail description about them on the datasheet.

 

ETH_PTPAUXIN, ETH_PTPCLKIN and ETH0_PTPPPS

 

I guess the "ETH0_PTPPPS" should be programmable pulse per second (PPS) output.

What are the others?
