Problem statement:
Implement a 10 digit down counter (Shown in the video).

Output Requirements:
As soon as the board is powered up or reset, CLCD display the title (Up Counter) on the first line
In second line, 9999999999 (10 digit number) starts decrementing
Decrement happens at constant rate (You may have lesser delay as possible since it's a 10 digit counter)
The counter stops after reaching count value of 0000000000

Pre-requisites:
You should have knowledge on,
I/O Port
CLCD

Objective:
To learn and understand
Basic working of the PORT
How to configure the PORT pins as Input and Output
How to configure the PORT pins as Digital
Interfacing CLCD as 8 or 4 bit mode
Instruction and Data mode
Read and Write mode
Commands

Inputs:
Program Cycles as Count

Notes / Additional Information:
Use program cycles to implement the above program.
A program cycle is the time taken to execute all the instructions from the start to end of the superloop
while (1)
{
/* Time taken to execute cycle the code written within this loop */
}

In this assignment you may consider the program cycles to obtain the scroll frequency
You should not use long data type for count
