+;* 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
