My customer already use S12XHY to develop the cluster project. Now they need to pass the 25KV ESD test but S12XHY is always reset.
So i suggest customer use the clock monitor reset different reset address to solve the cluster reset issue. I write a test code which will force MCU reset when external OSC signal is disturbed. But what i find is very strange. When i input a disturbed noise into the external OSC input pin first time, the MCU is reset with the same power on reset address. Then i continue to input the noise to the OSC input pin, the MCU is always into the SCM mode without any reset.
My quesions is:
1. how to into the clock monitor reset address?
2. Why MCU can not be reset when i input the noise into the OSC input pin after the first time?
