;* FILE NAME         : "M88DEF.INC" 
;* TITLE             : REGISTER/BIT DEFINITIONS FOR THE ATMEGA88 
;* DATE              : 14.01.2004
;* VERSION           : 
;* SUPPORT E-MAIL    : [e-mail]
;* TARGET MCU        : ATMEGA88 
;* 
;* 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
