I/O View Window Sections

The default view of the window is vertically split with peripheral groups in the top section and registers in the bottom section. Each peripheral typically has defined settings and value enumerations which can be displayed by expanding a register in the peripheral view (top section). The register view (bottom section) will display all registers which belong to a selected peripheral group. If no peripheral is selected, the view is empty. Each register can also be expanded to display the predefined value groupings that belong to the register.
