RELEASE: LPC1700CMSIS_31Mar2011
1./ Fix bug in I2C driver (customer feedback)
	Problem description: 
		I2C_MasterTransferData() is not able to 
		(1) Send, 
		(2) doing a repeated Start and 
		(3) starting to receive with one function call. 
		Problem is that the repeated start is not generated, but a retransmission of the 
		last word is startet. 
	Solve: change 
		I2Cx->I2CONCLR = I2C_I2CONCLR_SIC; 
		I2Cx->I2CONSET = I2C_I2CONSET_STA; 
	to 
		I2Cx->I2CONSET = I2C_I2CONSET_STA; 
		I2Cx->I2CONCLR = I2C_I2CONCLR_SIC; 
		in function I2C_Start ()
