Hi @Simon-Liu ,
McuErrorIsrNotification() just used for errors about voltage that cause interrupt.
Seem that at IP layer, you need to defined error callback by yourself. You need to create input parameter for the function Power_Ip_InstallNotificationsCallback() to install callback that you want to get when have error. For example: I'll create the function Power_ReportPowerErrorsCallback() that contains all callback functions for errors.
You can install it before Power_Init() called by:
Power_Ip_InstallNotificationsCallback(Power_ReportPowerErrorsCallback);
with Power_ReportPowerErrorsCallback() defined as:

So, you have as below:
