It is necessary to invoke the component method ConnectPin to connect a component to the shared pin. It is also necessary to invoke the main component method to connect pin back to the main component. In fact, the peripherals can usually operate simultaneously, but they have no connection to the shared pins unless the ConnectPin method is executed. In case that all components control the shared pin using one peripheral, it is not necessary to use the ConnectPin method.
Shared pins are presented in the Processor view as well. The component to pin connection line is red.
