TIMERs in NxpNfcRdLib SDK

Hi All,

I am using PN7462 in my design and NXpNfCRdLib v5.22.1 for firmware development.

I am running into an unusual issue where if I use 2 free Running timers NFC communication is unable to establish between Reader Writer and Card Emulator. If I reduce the free-running timer to 1 the system works smoothly. Is NxpNfcRdLib is using some timers which are causing this issue? 

Thanks, Jayesh.

Hello Jayesh,

I hope you are doing great, thank you for using our products.
Yes, as you are able to see in the UM10663, The receive and transmit HAL commands, require timers, some optional functions like "PHHAL_HW_RC663_OPTION_RXTX_TIMER_START" employs T0 and T1 timers.

Please keep in mind this limitation while using NXP Reader Library.
I'm sorry for the problems this might cause.
Thank you for your time, we really appreciate this!

Best Regards,
Fabian
