@Example description:
Purpose:
	This example describes how to calibrate real-time clock
Process:
    The calibration logic can periodically adjust the time counter either by not
    incrementing the ocunter, or by incrementing the counter by 2 instead 1. 
    This allow calibrating the RTC oscillator under some typical voltage and 
    temperature conditions without the need to externally trim the RTC 
    oscillator
	
    In this example:
	- Calibration setting:
	+ Calibration value = 5s;
	+ Direction: Forward calibration
	- Real-time clock setting:
	+ enable incrementing second counter interrupt
After each 5s, real-time clock will adjust automatically by incrementing the 
counter by 2 instead of 1. You can observe calibration process via serial 
display.

(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 on serial display
			
(Pls see "LPC17xx Example Description" document - chapter "Examples > RTC > 
Calibration" for more details)
		
@Tip:
	- Open \EWARM\*.eww project file to run example on IAR
	- Open \RVMDK\*.uvproj project file to run example on Keil
