+@Example description:
+	Purpose:
+		This example describes how to use Timer Match to generate specific time
+		in interrupt mode.
+	Process:
+		In this case, the specific time generated is 1s.
+		Timer configuration:
+			- Timer channel: 0
+			- Prescaler in microsecond value
+			- prescaler value = 100us
+		Match configuration:
+			- Use channel 0, MR0
+			- Match value = 10000
+			Because timer tick = prescaler = 100us
+			So match time = 100 * 10000 = 1000000us = 1s
+			- Timer reset after match
+			- Not stop MR0 when match
+			- Toggle MR0.0 when match
+			Because match time = 1s
+			So MAT0.0 will be toggled at frequency = 1Hz
+			- Generate match interrupt 
+		Whenever MR0 matches the value in TC register, match interrupt is occurs, TIMER0
+		will invoke interrupt service routine to handle interrupt, in this case, it will print 
+		a notice sentence into serial display. MAT0.0(P1.28) toggle and timer will be reseted.
+		
+		Note that: print data via UART can cause delay when match time set is too small.

+
+@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
+				
+	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 match interrupt notice on serial display
+				+ On MCB1700 board: MAT0.0(P1.28) connect with LED P1.28, so you can observe MAT0.0 toggle via 
+				LED P1.28 blinky process.
+				+ On IAR board: MAT0.0 signal can be observed by oscilloscope or wire P1.28 pin with LED1(P1.25)
+				
+		(Pls see "LPC17xx Example Description" document - chapter "Examples > TIMER > Interrupt_Match"
+		for more details)

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