;* 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
