	Atmel application note AVR313 ported for use with GCC
	by Mike Henning - September 2008

	Changes: 
	- Modified to use the ATMEGA16 instead of the obsolete 90S8515.
	- Changed the scan code table for english keyboards
	- Baud rate can be set under project configuration in Avr Studio.
	- The clr screen routine is not implemented - did not see the
	  point here.
---------------------------------------------------------------------
	A few improvements could be made:

	-Check kb parity bit and implement a timeout for keyboard scan
	-Move the call to decode out of the ISR
	-Add support for sending commands to the keyboard
	-Add support for extended keys
