We are using POR (P8) signal to reset the CPU. Here the reset to this pin is done by ORing the following reset sources. 1.Reset using Power-On Reset chip
2.Reset using Watch dog timer chip
3.Reset using Undervoltage/Overvoltage monitor chip
4.Reset using PMIC reset out
The same is shown in the attached images.
Now please let me know if my reset startegy is correct or not. Do I need to take care of something else.
