;* Title:		Register/Bit Definitions for the AT90S1200
;* Version:		1.1
;* Last updated:	97.07.04
;* Target:		AT90S1200
;*
;* Support E-mail:	avr@atmel.com
;*
;* DESCRIPTION
;* When including this file in the assembly program file, all I/O register	
;* names and I/O register bit names appearing in the data book can be used.
;* 
;* The Register names are represented by their hexadecimal addresses.
;* 
;* The Register Bit names are represented by their bit number (0-7).
;* 
;* Please observe the difference in using the bit names with instructions
;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc" 
;* (skip if bit in register set/cleared). The following example illustrates
;* this:
;* 
;* in	r16,PORTB		;read PORTB latch
;* sbr	r16,(1<<PB6)+(1<<PB5)	;set PB6 and PB5 (use masks, not bit#)
;* out  PORTB,r16		;output to PORTB
;*
;* in	r16,TIFR		;read the Timer Interrupt Flag Register
;* sbrc	r16,TOV0		;test the overflow flag (use bit#)
;* rjmp	TOV0_is_set		;jump if set
;* ...				;otherwise do something else
