Variables
const struct UART_INTERFACE	UART1_Drv
	Structure object of type UART_INTERFACE with the custom name given by the user in the Melody Driver User interface. The default name e.g. UART1 can be changed by the user in the UART user interface. This allows defining a structure with application specific name using the 'Custom Name' field. Application specific name allows the API Portability.
