SDMReadCtr Limit NTAG 424

Hi ,

What if the SDMReadCtr limit reaches FFFFFF? Would the NFC be unusable, or would it be set to 000000?

Thanks

Once the SDMReadCtr equals the SDMReadCtrLimit, no reading of the file with
ReadData or ISOReadBinary in not authenticated state can be executed

please refer to datasheet for more details.

Section 9.3
