Using Timer0, no prescaleer, and CTC mode, write a program that generates a square wave with a frequency of 50KHz. Assume XTAL = 8MHz.

int main()

{

Answer (DDRB, PORTB, PINB) = 0x Answer ; // PB3 (OC0) as output.

OCR0 = Answer ;

TCCR0 = 0xAnswer ; // CTC mode, no prescaler, toggle.

while (1); // stay here forever

}
