;* Date              : 2005-01-11

;*

;* 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<

;* 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
