Hello,
I was experimenting with configuring the SDA pins as GPIO using NFC commands on my NTAG5/NTA5332(OM2NTA5332). However, when I read the relevant register using the NFC Tools Android app, the value does not change as expected when I toggle the GPIO pins between high and low.
Could you please advise how I can restore the device to its default I2C state? I would like to revert any GPIO configuration and ensure the device operates normally on the I2C bus again.

FYI. NTAG 5 - Use of PWM, GPIO and event detection
This document show the details how to configure the GPIO.
