Hi,

https://www.nxp.com/docs/en/application-note/AN13219.pdf

The app note describes the default configuration for reader mode in chapter 4.4.1, figure 16 like this

But on the evaluation board, chapter 4.1, figure 2

https://www.nxp.com/docs/en/user-manual/UM11496.pdf

It has swapped places of RXP and RXN

I'm assuming that figure 2 is wrong here. Has somebody else thought about it?

Dear Vestin, 

As the TX and RX are "symmetrical" pins. Thus it does not matter if you connect TX1+RXN & TX2+RXP or TX1+RXP & TX2+RXN. 

But I agree it should be consistent in our documentation. We will update it in the next release. 

Many thanks for your input!

Best Regards

Tomas
