|
||
;* 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
