-;* 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\r
-;* \r
-;* Number : AVR000\r
-;* File Name : "m328Pdef.inc"\r
-;* Title : Register/Bit Definitions for the ATmega328P\r
-;* Date : 2008-04-10\r
-;* Version : 2.25\r
-;* Support E-mail : avr@atmel.com\r
-;* Target MCU : ATmega328P\r
-;* \r
-;* DESCRIPTION\r
-;* When including this file in the assembly program file, all I/O register \r
-;* names and I/O register bit names appearing in the data book can be used.\r
-;* In addition, the six registers forming the three data pointers X, Y and \r
-;* Z have been assigned names XL - ZH. Highest RAM address for Internal \r
-;* SRAM is also defined \r
-;* \r
-;* The Register names are represented by their hexadecimal address.\r
-;* \r
-;* The Register Bit names are represented by their bit number (0-7).\r
-;* \r
-;* Please observe the difference in using the bit names with instructions\r
-;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc"\r
-;* (skip if bit in register set/cleared). The following example illustrates\r
-;* this:\r
-;* \r
-;* in r16,PORTB ;read PORTB latch\r
-;* sbr r16,(1<<PB6)+(1<<PB5) ;set PB6 and PB5 (use masks, not bit#)\r
-;* out PORTB,r16 ;output to PORTB\r
-;* \r
-;* in r16,TIFR ;read the Timer Interrupt Flag Register\r
-;* sbrc r16,TOV0 ;test the overflow flag (use bit#)\r
-;* rjmp TOV0_is_set ;jump if set\r
-;* ... ;otherwise do something else\r
