+@Example description:
+	Purpose:
+		An example of I2C using polling mode to test the I2C driver.
+		Using I2C at mode I2C master/8bit on LPC1768 to communicate with
+		SC16IS750/760 Demo Board.
+	Process:
+		I2C is configured as master using polling mode.
+		I2C Clock Rate is set at 100K.
+				
+		I2C send commands to reset, config direction, validate value and handle SC16IS740 chip 
+		using polling mode.
+		On serial display:
+		- Press 'r' to print menu
+		- Press '1': send 0x00 value to IOStat register to turn on 8 LEDs on SC16IS740 board.
+		- Press '2': send 0xFF value to IOStat register to turn off 8 LEDs on SC16IS740 board.
+		
+		(Pls see two pdf file at SPI/sc16is750:
+			- SC16IS740_750_760_6.pdf
+			- schematics.sc16is750.demo.board.pdf
+		for more information about SC16IS740 board)

+@Directory contents:
+	\EWARM: includes EWARM (IAR) project and configuration files
+	\Keil:	includes RVMDK (Keil)project and configuration files 
+	
+	lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example 
+	makefile: Example's makefile (to build with GNU toolchain)
+	i2c_polling_test.c: Main program
+
+@How to run:
+	Hardware configuration:		
+		This example was tested on:
+			Keil MCB1700 with LPC1768 vers.1
+				These jumpers must be configured as following:
+				- VDDIO: ON
+				- VDDREGS: ON 
+				- VBUS: ON
+				- Remain jumpers: OFF
+			IAR LPC1768 KickStart vers.A
+				These jumpers must be configured as following:
+				- PWR_SEL: depend on power source
+				- DBG_EN : ON
+				- Remain jumpers: OFF
+				
+			SC16IS750 board:
+			 	These jumpers must be configured as following:
+			 	- JP2: 1-2 (I2C)
+			 	- JP16: 2-3 (hard reset)
+			 	- Remain jumper: OFF
+			 	
+	I2C connection:
+			- SDA and SCL pin in two board connect in "pin-to-pin" style: SDA <-> SDA, SCL <-> SCKss 
+			- Common power source 3.3V and ground must be connected together between two board.	
+		+ For I2C0:
+			SDA: P0.27
+			SCL: P0.28
+		+ For I2C2:
+			SDA: P0.10	
+			SCL: P0.11	
+				
+	Serial display configuration:(e.g: TeraTerm, Hyperterminal, Flash Magic...) 
+		– 115200bps 
+		– 8 data bit 
+		– No parity 
+		– 1 stop bit 
+		– No flow control 
+	
+	Running mode:
+		This example can run on RAM/ROM mode.
+					
+		Note: If want to burn hex file to board by using Flash Magic, these jumpers need
+		to be connected:
+			- MCB1700 with LPC1768 ver.1:
+				+ RST: ON
+				+ ISP: ON
+			- IAR LPC1768 KickStart vers.A:
+				+ RST_E: ON
+				+ ISP_E: ON
+						
+		(Please reference "LPC1000 Software Development Toolchain" - chapter 4 "Creating and working with
+		LPC1000CMSIS project" for more information)
+	
+	Step to run:
+		- Step 1: Choose I2C peripheral by setting 'USEDI2CDEV'
+		- Step 2: Build example.
+		- Step 3: Burn hex file into board (if run on ROM mode)
+		- Step 4: Connect UART0 on this board to COM port on your computer
+		- Step 5: Configure hardware and serial display as above instruction 
+		- Step 6: Run example, and control the I2C transmition and reception via UART display tool.
+		
+		(Pls see "LPC17xx Example Description" document - chapter "Examples > I2C > sc16is750_polling"
+		for more details)

+@Tip:
+	- Open \EWARM\*.eww project file to run example on IAR
+	- Open \RVMDK\*.uvproj project file to run example on Keil
