,,,;* 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
