When observing only a subset of registers on a SoC with many SFRs the following inconveniences can be encountered:
Create a custom SFR window that contains only the registers you select.
1. Open View | Debug | SFR | New Custom SFR.
2. Give it a meaningful name. An empty SFR Window will open.
3. Drag and drop items to the new window.
You can filter SFRs by name using a filter.
1. Right-click on the SFR window.
2. Select Show Filter.
3. Write the desired filter. The window will only show SFRs containing that text.
For a more detailed presentation of the SFR Window refer to the Tutorial – Special Function Registers in winIDEA.
