;*************************************************************************** ;* A P P L I C A T I O N N O T E F O R T H E A V R F A M I L Y ;* ;* Number :AVR000 ;* File Name :"m8def.inc" ;* Title :Register/Bit Definitions for the ATmega8 ;* Date :07.09.2001 ;* Version :1.00 ;* Support telephone :+47 72 88 43 88 (ATMEL Norway) ;* Support fax :+47 72 88 43 99 (ATMEL Norway) ;* Support E-mail :avr@atmel.no ;* Target MCU :ATmega8 ;* ;* 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 ;*************************************************************************** ;***** Specify Device .device ATmega8 ;***** I/O Register Definitions .equ SREG =$3f .equ SPH =$3e .equ SPL =$3d .equ GIMSK =$3b .equ GICR =$3b ; new name for GIMSK .equ GIFR =$3a .equ TIMSK =$39 .equ TIFR =$38 .equ SPMCR =$37 .equ I2CR =$36 .equ TWCR =$36 .equ MCUCR =$35 .equ MCUSR =$34 ; For compatibility, .equ MCUCSR =$34 ; keep both names until further .equ TCCR0 =$33 .equ TCNT0 =$32 .equ OSCCAL =$31 .equ SFIOR =$30 .equ TCCR1A =$2f .equ TCCR1B =$2e .equ TCNT1H =$2d .equ TCNT1L =$2c .equ OCR1AH =$2b .equ OCR1AL =$2a .equ OCR1BH =$29 .equ OCR1BL =$28 .equ ICR1H =$27 .equ ICR1L =$26 .equ TCCR2 =$25 .equ TCNT2 =$24 .equ OCR2 =$23 .equ ASSR =$22 .equ WDTCR =$21 .equ UBRRH =$20 ; Note!
