**Function name: IRQ7()

**Input: none

**Output: none

**Description: this function works when UART receive or send a byte. But SPCE061
			  seems just have receive data interrupt servies, but no send data 
			  interrupt sevies. when a byte was read interrupt flag will automatically
			  cleared

**Return: none
