How to customize tags

JesseChan — Tue, 08 Apr 2025 06:27:17 GMT

The chip signal I am using is NTA53321G0FHKZ. It uses the IIC interface.I want to create a label that can be customized for reading and writing.I once tried configuring the official SRAM pass-through routine and successfully wrote short tags using NXP TagWritter. However, I attempted to read memory 0x2000 through the IIC interface but was unable to do so.The following are the problems I encountered.

1.I want to know which registers need to be set and what values these registers are set to.

2.I want to know which memory address I need to write the label I want to set.

3.What format should the data written to memory follow.

Meanwhile, I want to lock the memory to prevent the NFC interface from modifying the tags I have defined

Thanks， I have already resolved the issue. I have another question, I want to set it to standby mode. When I set this position, it seemed to have no effect. The power consumption has not decreased. Do I need to reboot？how to reboot？
