Write a register level program to calculate each
bit address of Port F Data register, where the red,
green, blue LEDs are connected. Also light each
led with different delay 1 sec, 2sec, 3 sec.
How many cycle do we need to create the delay of 1
sec, 2 sec, and 3 sec. Read the datasheet and
identify the clock frequency on the GPIO port.
