When the Windowed mode of operation is enabled in Doze mode, a window violation error is issued even though the window is open and has been armed. This condition occurs only when the window size is set to a value other than 100% open.
Method 1:
Use the Windowed mode of operation in any mode other than Doze. If disabling the Doze mode is not an option, use the WWDT module without the window being enabled.
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.
