A special Function Register (SFR) is a register within a microcontroller that controls or monitors various aspects of its function, e.g. GPIO control registers, or processor status registers.
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.
For a more detailed presentation of the SFR Window refer to the Tutorial – Special Function Registers in winIDEA.
