9  STACK POINTER  PROGRAM COUNTER  INSTRUCTION REGISTER  INSTRUCTION DECODER  GENERAL PORPUSE REGISTER  32 REGISTER  ALU  STATUS REGISTER

10  I  GLOBAL INTERUPT ENABLE  T  BIT COPY STORAGE  COPY BIT ANTAR BIT REGISTER  H  HALF CARRY FLAG  UNTUK MENUNJUKAN TIDAK ADANYA SETENGAH CARRY PADA OPERASI ARTIMATIKA  S  SIGN BIT  MERUPAKAN HASIL EOR ANTARA FLAG –N (NEGATIF) DAN FLAG V (KOMPLEMEN DUA OVERFLOW)  V  TWO`S COMPONENT OVERFLOW FLAG  PERHITUNGAN SEBELUMNYA MENYEBABKAN OVERFLOW  N  NEGATIVE FLAG  DISET JIKA HASIL OPERASI MATEMATIS MENGHASILKAN NEGATIF  Z  ZERO FLAG  DISET JIKA HASIL OPERASI MATEMATIS MENGHASILKAN BILANGAN 0  C  CARRY FLAG  DISET JIKA OPERASI MENGHASILKAN CARRY

11  FLASH MEMORY  SRAM  EEPROM

12  TWI  SPI  UASRT  ISP

13  COUNTER  TIMER  WATCHDOG TIMER

14  EXTERNAL  INTERNAL

15  8 BIT BIDIRECTIONAL  PORT A, PORTB, PORT C DAN PORT D

16  ADC  PWM

17

18  PORT A  I/O 8BIT BIDIRECTIONAL  OUTPUT ARUS 20mA  PORT B  I/O 8 BIT BIDIRECTIONAL  OUTPUT ARUS 20 mA  MEMILIKI FUNGSI ALTERNATIF  PORT C  I/O 8 BIT BIDIRECTIONAL  OUTPUT ARUS 20 mA  PORT D  I/O 8 BIT BIDIRECTIONAL  OUTPUT ARUS 20 mA  MEMILIKI FUNGSI ALTERNATIF

19 PORT PINFUNGSI PB0T0 = TIMER/COUNTER 0 EXTERNAL COUNTER INPUT PB1T1 = TIMER/COUNTER 1 EXTERNAL COUNTER INPUT PB2AIN0 = ANALOG COMPARATOR POSITIVE INPUT PB3AIN1 = ANALOG COMPARATOR NEGATIVE INPUT PB4SS = SPI SLAVE SELECT INPUT PB5MOSI = SPI BUS MASTER OUTPUT/SLAVE INPUT PB6MISO = SPI BUS MASTER INPUT/SLAVE OUTPUT PB7SCK = SPI BUS SERIAL CLOCK

20 PORT PINFUNGSI PD0RDX (UART INPUT LINE) PD1TDX (UART OUTPUT LINE) PD2INT0 = EXTERNAL INTERRUPT 0 INPUT PD3INT1 = EXTERNAL INTERRUPT 1 INPUT PD4OC1B = TIMER/COUNTER1 OUTPUT COMPARE B MATCH OUTPUT PD5OC1A = TIMER/COUNTER1 OUTPUT COMPARE A MATCH OUTPUT PD6ICP = TIMER/COUNTER1 INPUT CAPTURE PIN PD7OC2 TIMER/COUNTER OUTPUT COMPARE MATCH OUPUT

21  RESET PIN 9  XTAL1 DAN XTAL 2  INPUT OSILATOR  AVCC  INPUT TEGANGAN UNTUK ADC  AREF  REFERENSI ADC  AGND  ANALOG GROUND
