   Z-World, 2002

	This program is used with RCM3000 series controllers
	with prototyping boards.

	The sample library, rcm3000.lib, contains a brdInit()
	function which initializes port pins. Modify this
	function to fit your application.

	An optional LCD/Keypad Module is required to run this
	program.  #define PORTA_AUX_IO at top of program to
	enable external I/O bus for LCD/Keypad operations.
	
	Description
	===========
	This sample program demonstrates the use of the external
	I/O bus with the controller using an LCD/Keypad Module.
	The program will light-up an LED and will display a message
	on the LCD when a switch press is detected.

	DS1 and DS2 LED's on the proto-board will also light-up
	on a switch press.
	
	Instructions
	============
	1. Compile and run this program.
	2. Press and hold DS1 or DS2 on the prototyping board to
	   see a message displayed on the LCD and light up an LED.
	   Here's a list of how the switches are connected.
