+@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.

+	rs485_slave.c: Main program
+
+@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
+				
+		RS485 Connection:
+		Pls see the 'Transceiver_Master.png' in this directory for wiring information.				
+	
+	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: Connect RS485 between master board and slave board (using ADM485)
+		- Step 5: Run example and using Serial display to monitor the communication between master and slave.
+		Note: The RS485 slave device must initialize first.
+		
+		(Pls see "LPC17xx Example Description" document - chapter "Examples > UART > 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
