Hi all:

My IC is easy to malfunction due to EMI interference.
I did two experiments to verify it:
based on the same PCB Board and the experiment environment,
I compare my chip and competitor's, the result shows my chip
easy to effect by EMI.

The malfunction :
  1. some Register values are error
  2. Outputs Interrupt for no reason

My chip communication interface is I2C.

If you have any relevant paper or doc, please sharing to me.
If you have any suggestion, please let me know.


Thanks.

Many ways to fail; start by learning to provoke the problem(s)
repeatably and at will. Then you can determine causes and
solutions.

Collecting a basket of conjectures only brings anecdotes, not
understanding. And you'd like to understand, so as not to
repeat.
