+;* 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.
+;* In addition, the six registers forming the three data pointers X, Y and
+;* Z have been assigned names XL - ZH. Highest RAM address for Internal
+;* SRAM is also defined
+;*
+;* The Register names are represented by their hexadecimal address.
+;*
+;* 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
