				;* 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				;* 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
