ISM6HG256X / Shock event

Hi, 

 

we use on a design a ISM6HG256X. We want to detect a shock end event using the interrupt INT2.

We use this configuration :

    * INT2_HG_WU = 0

    * INT1_HG_WU = 0

    * INT2_HG_SHOCK_CHANGE = 1 

    * INT1_HG_SHOCK_CHANGE = 0

Logically, we should have an interrupt INT2 only when the shock event end is detected. In fact, we have an interrupt at wake_up event and at the shock end and sometimes we have interrupt on INT1. 

We use a STEVAL - MKI248KA to evaluate the ISM6.

Do you have some tips to solve this problem?
