;* 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 : "tn2313Adef.inc"
;* Title : Register/Bit Definitions for the ATtiny2313A
;* Date : 2011-02-09
;* Version : 2.35
;* Support E-mail : avr@atmel.com
;* Target MCU : ATtiny2313A
;*
;* 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

RESOURCE USE INFORMATION
------------------------
Notice:
The register and instruction counts are symbol table hit counts,
and hence implicitly used resources are not counted, eg, the
'lpm' instruction without operands implicitly uses r0 and z,
none of which are counted.
x,y,z are separate entities in the symbol table and are
counted separately from r26..r31 here.
.dseg memory usage only counts static data declared with .byte
