+@Example description:
+	Purpose:
+		This example describes how to enter system in PowerDown mode and wake-up it 
+		by using NMI (Non-Maskable Interrupt)
+	Process:
+		NMI(Non-Maskable Interrupt) is the highest priority interrupt, it takes effect 
+		as soon as it registers. When connect, a logic 1 on the pin will cause the NMI 
+		to be processed.
+		Select P2.10 as NMI pin
+		At the first time, sure that NMI pin has logic 1 because if it connects with
+		ground -> ISP is pulled low, system will enter in ISP mode.  
+		After that, call CLKPWR_PowerDown() to enter system in PowerDown mode 
+		(Note: In this time, NMI pin must be connected with ground to disable NMI 
+		interrupt). 
+		When system is PowerDowning..., pulls up NMI to logic 1, NMI occurs 
+		and wake-up system.

+	makefile: Example's makefile (to build with GNU toolchain)
+	nmi_powerdown.c: Main program
+
+@How to run:
+	Hardware configuration:		
+		This example was tested only 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
+				
+		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: Build example.
+		- Step 2: Burn hex file into board (if run on ROM mode)
+		- Step 3: Connect UART0 on this board to COM port on your computer
+		- Step 4: Configure hardware and serial display as above instruction 
+		- Step 5: Run example and observe on serial display
+					+ First, sure that NMI pin (P2.10) has logic 1 
+					+ Press "RESET" button to run example
+					+ Connect P2.10 with ground to disable NMI interrupt
+					+ Press '1' to enter system in DeepSleep mode
+					+ After sleeping..., pull up P2.10 to generate NMI interrupt to wake-up system
+			
+		(Pls see "LPC17xx Example Description" document - chapter "Examples > PWR > NMI_PowerDown"
+		for more details)
+		
+@Tip:
+	- Open \EWARM\*.eww project file to run example on IAR
+	- Open \RVMDK\*.uvproj project file to run example on Keil
+	- On MCB1700 board, it doesn't have a wiring ground pin output, so you can use UMODE.3 instead
+	(reference MCB1700 datasheet for more information)
