@Example description:
Purpose:
	This example describes how to use Timer Match to generate 2 different
	frequency signals.
Process:
	1) Initialize COM1 and display information menu.
	2) Ask user to input frequency for channel 1 (MAT0.0) and channel 2 
           (MAT2.0) Configure J2 pin 19 (P1.28) as MAT0.0 and J2 pin 5 (P0.6) as
           MAT2.0.
	3) Configure TIMER0 and TIMER2 as follow:
	      - Prescale register = 1 us.
	      - Match register = 1 / ((channel1 or channel2 frequency)*100us*2)
				 = 500000 / channel1 or channel2 freuqency
	      - No interrupt, no stop but reset timer counter on match.
	4) Start TIMER0 and TIMER2.
	      Press ESC if we intend to test with other frequencies.
	      TIMER0 and TIMER2 are de-initialized.

lpc17xx_libcfg.h: Library configuration file - include needed driver library for 
this example makefile: Example's makefile (to build with GNU toolchain)
gen_diff_freqs.c: Main program

@How to run:
Hardware configuration:		
				
Serial display configuration: (e.g: TeraTerm, Hyperterminal, Flash Magic...) 
	– 115200bps 
	– 8 data bit 
	– No parity 
	– 1 stop bit 
	– No flow control 
	
Running mode:
ROM(FLASH)mode: This example can be run on ROM mode with debugger or standalone 
                after burning. All files in each example must be built to .hex 
                file. This file will be burned into ROM(Flash) memory through an
                external tool (i.e: Flash Magic...) befor running.
					
(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 COM1 on the Lincoln 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 and MAT2.0 waveform by oscilloscope

Gen_Diff_Freqs" for more details)
		
@Tip:
	- Open \EWARM\*.eww project file to run example on IAR
	- Open \RVMDK\*.uvproj project file to run example on Keil
