Write an AVR C program using Timer 1 interrupt to create a square wave of 1Hz on pin PB7 while sending data from PORTC to PORTD. Assume XTAL=8MHz. Problem 2 Assume that the INTO pin is connected to a switch. Write an AVR C program in which it goes high, the content of PORTC increases by one. Problem 3 Using pin change interrupt, write an AVR C program that sends the value of PORTC to PORTD whenever the value of PORTC changes. Problem 4 Assume that Timer 1 is programmed for CTC mode, TCNT1=$0001, OCR1A = $F501 and OCIE1A bit is enabled. Explain how the interrupt is activated. Problem 5 Assume that Timer 1 is programmed for Normal mode, TCNT1=$E8FF, TOIE1 bit is enabled. Explain how the interrupt is activated. Problem 6 Explain the role of INTFO and INTO in executing external interrupt 0. Problem 7 Explain the difference between low-level and falling edge - triggered Write an AVR C program using Timer 1 interrupt to create a square wave of 1Hz on pin PB7 while sending data from PORTC to PORTD.
