UART peripheral is typically used to control an external device connected to the [N] device via the HW UART interface. The following picture shows an example where the [C] writes by UART Write & Read DPA Request a text “Hello” to the UART peripheral at [N]. There is a terminal (external device) connected using UART to the [N]. Text “Hello” is then displayed at the terminal and text “Hi” (in this example the terminal automatically answers “Hi” to “Hello”) is read back to the [C] at the corresponding DPA Request.
