Assume the XTAL frequency is $10MHz,$ Write an AVR assembly language

program to read data from Port $C,$ wait for $\frac{1}{4}$ second and then compare the data from Port $C$

with $100.$ If the data is less than or equal to $100,$ send character $\text{'}Y\text{'}$ to port $D$ otherwise send

character $\text{'}N\text{'}$ to port $D.$

a$).$ Use timer$/$counter of your choice in Normal Mode

b$)$ Use timer$/$counter of your choice in CTC Mode
