Function Prototype : void ConfigIntUART2(unsigned int config)

Include            : uart.h
 
Description        : This function configures the UART Interrupts.
 
Arguments          : config - Individual interrupt enable/disable information 
                     as defined below
					 Receive Interrupt enable					
					    UART_RX_INT_EN					
					    UART_RX_INT_DIS					
					 Receive Interrupt Priority					
					    UART_RX_INT_PR0					
					    UART_RX_INT_PR1				
					    UART_RX_INT_PR2					
					    UART_RX_INT_PR3					
					    UART_RX_INT_PR4					
					    UART_RX_INT_PR5					
					    UART_RX_INT_PR6					
					    UART_RX_INT_PR7					
					 Transmit Interrupt enable					
					    UART_TX_INT_EN					
					    UART_TX_INT_DIS					
					 Transmit Interrupt Priority					
					    UART_TX_INT_PR0					
					    UART_TX_INT_PR1					
					    UART_TX_INT_PR2					
					    UART_TX_INT_PR3					
					    UART_TX_INT_PR4					
					    UART_TX_INT_PR5					
					    UART_TX_INT_PR6					
					    UART_TX_INT_PR7
 
Return Value       : None
 
Remarks            : This function enables/disables the UART transmit and
                     receive interrupts and sets the interrupt priorities.
