The Peripherals view contains a table showing a list of available peripherals on the currently selected processor that can be configured by the Peripherals Tool. In case of multicore processors, the displayed peripherals are also core-specific.
Each instance of a peripheral (for example, UART0) occupies one row. First column contains peripheral name and a checkbox indicating whether the peripheral is used by any component instance.
De-selecting a previously-selected instance disables it. You can enable it by selecting the checkbox, or by clicking the switch in the settings editor of the component instance.
Second column contains a name of component instance handling the peripheral. This name is freely customizable in the settings editor and it is used in generated code.
Double-click on the second column opens the editor for the component instance.
