;* Number : AVR000
;* File Name : "2323def.inc"
;* Title : Register/Bit Definitions for the AT90S2323
;* Date : 2005-01-11
;* Version : 2.14
;* Support E-mail : avr@atmel.com
;* Target MCU : AT90S2323
;*
;* 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
