I2C timeout when using NT3H2111

Hello.

 

I've implemented bidirectional communication using SRAM as described in AN11579 using the NT3H2111 chip.

 

This works as a charm most of the times, but occasionally a command sent via I2C times out, and then the chip becomes unresponsive, and all subsequent commands times out.

 

I’ve tried to perform the soft reset as described in 9.3 p 42 in the manual, but that does not solve the issue.

 

What can I do except resetting the whole device?

 

Regards
