Can I access the PDM signals on a MIMXRT1170-EVK board?

Hi,

I want to start to use the RT1170. I'm thinking of buying the MIMXRT1170-EVK evaluation board for the development. But I need to connect multiple microphones to the PDM pins of the RT1170. I can not find out if these pins are accessible.

I found the schematic of the MIMXRT1170-EVK board. But the PDM pins are not mentioned. The reference manual does not tell me which pins to look for.

Any advice how to do this?

Ah, found it. I didn't look good enough.
In the reference manual chapter 11 about pin multiplexing you can find the pin candidates for those pins.
And so I found the signals on the evaluation board. There are even microphones on the board!
