@Example description:
Purpose:
	This example describes how to use RS485 functionality on UART1 of LPC1768
	in slave mode.
Process:	
	RS485 function on UART1 acts as slave mode on RS485 bus.
	RS485 Slave device in this example can operate in separate mode
	as following:
		- Slave device always receives all frames on RS485 bus, 
                  regardless data frame (9 bit mode with parity stick '0') or 
                  slave address frame (9 bit mode with parity stick '1').
		- Slave device does not always receive all frames on RS485 bus. 
                  In this case, only slave address frame can trigger an 
                  interrupt event, then slave device can accept the following 
                  data frame by determine that slave address frame is its own 
                  address or not(implemented by software).
		- Slave device is in auto slave address detection mode. In this 
                  mode, only slave address frame with slave address value that 
                  matched with pre-configured slave address will be accepted 
                  automatically (by hardware)and trigger an interrupt callback 
                  event to handle following data frames.

@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:
This example can run on RAM/ROM mode.
					
(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: Connect RS485 between master board and slave board 
	- Step 5: Run example and using Serial display to monitor the 
                  communication between master and slave.
	Note: The RS485 slave device must initialize first.

RS485_Slave" for more details)
		
@Tip:
	- Open \EWARM\*.eww project file to run example on IAR
	- Open \RVMDK\*.uvproj project file to run example on Keil
