How it works
Based from https://wokwi.com/projects/341279123277087315
On power-up, the 7-segment display should display the text PILIPINASLASALLE one at a time per clock cycle. The "dp" output toggles every clock cycle.
How to test
Default mode: Set the clock input to a low frequency such as 1 Hz to see the text transition per clock cycle.
Manual mode: Set the input pin 7 to HIGH and toggle input pins 0-3. The character displayed for each input combination should be according to the table above.
