You are required to use port programming in this question. Use Port B to connect the 7-segment display (shown below) to your microcontroller.

For example: you may choose to connect pin A of the 7-segment to Port B Pin 1, and so on.

Clearly label the port b pin number that you have selected to represent the pins of the 7- segment display.

7-Segment Display Pin:	Port B Pin
A
B
C
D
E
F
G

Write a program that displays the numbers from 0 to 9 with a delay of 1 second between each number. After reaching 9, the numbers should count down to 0.
