MCU not exit-ing the i2c driver

I am using MKL03Z with a NTAG I2C Plus chip hooked up to the I2C bus.

Very often it happens that after a trasmit from the MCU to the NTAG, the function "I2C_MasterTransferBlocking()" in file fsl_i2c.c does not return. It gets stuck in the following while and never exits:



What could be the reason and how can I fix it?


Looking forward to getting some help.


Best regards,
