How to connect an IO pin via XBAR to ADC_ENV to trigger ADC conversions?

I'm using a iMXRT1011 MCU and I need so synchronize ADC conversions to an external source. 

I want to connect a sample clock to some IO pin and make the ADC start conversions on that sample clock.

I did read somewhere that one would need to connect the IO via the XBAR to the ADC_ETC module. But I see no XBAR inputs that connect to IO pins.

So is it possible?

Hi @simmania,

I presume you read about this on an RT1050 or RT1060 related post, since these devices do have IOMUX_XBAR_INxx signals. The RT1010, on the other hand, does not have an IOMUX_XBAR_IN signal, so it is not possible for the RT1010.
