Microcontroller Module2-Part1

There are total of ............. ports in ATmega32

All of the ATMega32 have 8 pins

• True

• False

Upon Powerup , the I/O pins are configured as output ports

• True

• False

To make port B an output we must place​​................... in register ​ ..........................

• 0x00 in DDRB

• 0xFF in DDRB

• 0xFF in DDRx

• 0x11 in DDRB

We use PORTx register to send data to output

• True

• False

We use PINx to bring data into the CPU from AVR pins

• True

• False

After the execution of following commands

LDI R16, 0X00

OUT DDRB, R1

• The PORTB act as a output register

• The PORTB act as a input register

• The PORTB act as a control registe

• All ports act as a input register
