NTA5332 How To Restore

[fei6688]

When using the NTA5332 for development, the NFC read/write configuration file has been set to disable via nfc. After that, an I2C abnormality caused communication failure with I2C. After recovery, communication with the NTA5332 via I2C is not possible, and NFC can no longer be configured. Is there any way to restore it to factory settings? It is suspected that the I2C abnormality caused an issue in the configuration, and I2C communication remains unavailable.

Do you mean the I2C bus stuck?  Have you try the I²C bus recovery (9 SCL pulses)?

No，If neither the I2C nor the NFC interface of the NTA5332 chip can communicate, it may be due to incorrect configuration of the chip. Are there any methods to restore it to factory settings?
