1.10.1 Window Operation in Doze Mode
When enabling the Windowed operation mode in Doze mode, a window violation error is issued even though the window is open and armed. This condition occurs only when the window size is set to a value other than 100% open.
Work around
Method 1:
Use the Windowed operation mode in any mode other than Doze. If disabling the Doze mode is not an option, use the WWDT module without enabling the window.
Method 2:
If the device is in Doze mode, perform the arming process for the window in Normal mode and return to the Doze mode.
Method 3:
If there is an Interrupt Service Routine (ISR) in the application code, the arming within the window can be done inside the ISR with the ROI bit of the CPUDOZE register being set.
