@Example description:
	Purpose:
		This example describes how to use Timer Match to generate different
		delay signals.
	Process:
		1) Initialize UART0 and display information menu.
		2) Ask user to input delay time for T1 and T2 (unit in ms)
		   Configure P1.28 as MAT0.0
		3) Configure TIMER0:
			- Prescale register = 100 us.
			- Match register = T1/100us = T1 ms/ 100us = T1*10
			- Interrupt, no stop, no reset timer counter on match.
		4) Timer0 ISR:
			- Stop timer.
			- Reset and synchronize timer and prescal counter.
			- Update new timer match value.
			- Start timer.
		5) Start TIMER0.
		   Press ESC if we intend to test with other frequencies.
		   TIMER0 and TIMER0 interrupt service are de-initialized.

@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 MAT0.0 waveform by oscilloscope.
		(Pls see "LPC17xx Example Description" document - chapter "Examples > TIMER > Gen_Diff_Delay"
		for more details)
