I have an issue I am trying to track down and am wondering if anyone here has any insight. The entire chip (CY8C9540) crashes/resets when toggling certain input pins (P1_B6 and P1_B7). Every pin on that port is configured the same (pulled up) and are also used as inputs, but these two will periodically (roughly 50% of the time) reset the entire chip when pulled low. The other inputs work fine and as expected. The only thing I can think of is maybe the problem is related to these pins also sharing I2C address functionality, but pin A0 is pulled hard to ground, so they should be out of that picture. Has anyone else ran into this issue of have any ideas for me to try? Thanks.
