Hello Jin,

I don't fully understand the question at hand. "Loopback" (I presume this is what you meant by 'lookback') mode is typically used for serial communication interfaces like UART, I2C, CAN etc. Not just as a standard GIO.

Yes, you are right, it is Loopback, for my understanding, GIO loopback is also a diagnostic mechanism for general Output pin, am I correct ? But what is the safety mechanism for GIO input pin ?

I am not familiar with this kind of diagnostic mechanism, can you point to the datasheet or TRM section that outlines this so I can review what you are asking about?
