/*********************************************************************
Function Prototype : void CloseUART4(void)
  
Include            : uart.h
 
Description        : This function disables the UART and clears the
                     interrupt enable and flag bits.  
  
Arguments          : None
 
Return Value       : None
 
Remarks            : This function first turns off the UART module and
                     then disables the UART transmit and receive interrupts.
                     The Interrupt Flag bits are also cleared.
