MM9Z1_638D1 D2D Interface Time Out in Background Debug Mode?

I observed a D2D interface timeout on a MM9Z1_638D1 when I am in a breakpoint or just watching many variables with automatic refresh during running. A colleague observed the same in some setups during data transfers to the EEPROM.

Unfortunately I do not really understand how this interfaces works exactly. As a workaround I currently just auto-acknowledge the TIMEF in D2DSTAT0.

When exactly can such a timeout occur? And when is it safe to just auto-acknowledge it?





P.S.: I am new to the MCU.
