-* Title: LED Light Blinking
-*
-* Objective: CMPEN 472 Homework 2 in-class-room demonstration
-* program
-*
-* Revision: V1.0
-*
-* Date: Jan. 29, 2025
-*
-* Programmer: Jacob McDonnell
-*
-* Company: The Pennsylvania State University
-* Department of Computer Science and Engineering
-*
-* Algorithm: Simple Parallel I/O use and time delay-loop demo
-*
-* Register Use: A: LED Light on/off state and Switch 1 on/off state
-* X,Y: Delay and loop counters
-*
-* Memory Use: RAM Locations from $3000 for data,
-* RAM Locations from $3100 for program
-*
-* Input: Parameters hard-coded in the program - PORTB
-* Switch 1 at PORTB bit 0
-* Switch 2 at PORTB bit 1
-* Switch 3 at PORTB bit 2
-* Switch 4 at PORTB bit 3
-*
-* Output: LED 1 at PORTB bit 4
-* LED 2 at PORTB bit 5
-* LED 3 at PORTB bit 6
-* LED 4 at PORTB bit 7
-*
-* Observation: This program that blinks LEDs and blinking period can
-* be changed with the delay loop counter value. When switch 1
-* is not pressed, LEDs 1 and 4 will blink alternately for 1
-* second each. When switch 1 is pressed LEDs 1, 2, 3, & 4 will
-* all turn on at the same time for 1 second and turn off at the
-* same time for 1 second.
-*
-* Note: All Homework programs MUST have comments similar
-* to this Homework 2 program. So, please use those
-* comment format for all your subsequent CMPEN472
-* Homework programs.
-*
-* Adding more explanations and comments help you and
-* others to understnad your program later.
-*
-* Comments: This program is developed and simulated using CodeWarrior
-* development software and targeted for Axion
-* Manufacturing's CSM-12C128 board running at 24MHz.

-* Memory Use: RAM Locations from $3000 for data,
-* RAM Locations from $3100 for program
-*
-* Input: Parameters hard-coded in the program - PORTB
-* Switch 1 at PORTB bit 0
-* Switch 2 at PORTB bit 1
-* Switch 3 at PORTB bit 2
-* Switch 4 at PORTB bit 3
-*
-* Output: LED 1 at PORTB bit 4
-* LED 2 at PORTB bit 5

-* Title: LED Light Dimmer
-*
-* Objective: CMPEN 472 Homework 3
-*
-* Revision: V1.0
-*
-* Date: Feb. 5, 2025
-*
-* Programmer: Jacob McDonnell
-*
-* Company: The Pennsylvania State University
-* Department of Computer Science and Engineering
-*
-* Algorithm: Simple Parallel I/O use and time delay-loop demo
-*
-* Register Use: A: LED Light on/off state and Switch 1 on/off state
-* X: Delay loop counter
-*
-* Memory Use: RAM Locations from $3000 for data,
-* RAM Locations from $3100 for program
-*
-* Input: Parameters hard-coded in the program - PORTB
-* Switch 1 at PORTB bit 0
-* Switch 2 at PORTB bit 1
-* Switch 3 at PORTB bit 2
-* Switch 4 at PORTB bit 3
-*
-* Output: LED 1 at PORTB bit 4
-* LED 2 at PORTB bit 5
-* LED 3 at PORTB bit 6
-* LED 4 at PORTB bit 7
-*
-* Observation: This program will dim the LED4 to either 5% when the
-* switch is not pressed and 15% when the switch is pressed.
-*
-* Note: ON CSM-12C128 board,
-* Switch 1 is at PORTB bit 0, and

-* Title: LED Light Dimmer
-*
-* Objective: CMPEN 472 Homework 3
-*
-* Revision: V1.0
-*
-* Date: Feb. 5, 2025
-*
-* Programmer: Jacob McDonnell
-*
-* Company: The Pennsylvania State University
-* Department of Computer Science and Engineering
-*
-* Algorithm: Simple Parallel I/O use and time delay-loop demo
-*
-* Register Use: A: LED Light on/off state and Switch 1 on/off state
-* X: Delay loop counter
-*
-* Memory Use: RAM Locations from $3000 for data,
-* RAM Locations from $3100 for program
-*
-* Input: Parameters hard-coded in the program - PORTB
-* Switch 1 at PORTB bit 0
-* Switch 2 at PORTB bit 1
-* Switch 3 at PORTB bit 2
-* Switch 4 at PORTB bit 3
-*
-* Output: LED 1 at PORTB bit 4
-* LED 2 at PORTB bit 5
-* LED 3 at PORTB bit 6
-* LED 4 at PORTB bit 7
-*
-* Observation: This program will dim the LED4 to either 5% when the
-* switch is not pressed and 15% when the switch is pressed.
-*
-* Note: ON CSM-12C128 board,
-* Switch 1 is at PORTB bit 0, and
-* LED 4 is at PORTB bit 7.
-*
-* Comments: This program is developed and simulated using CodeWarrior
-* development software and targeted for Axion
-* Manufacturing's CSM-12C128 board running at 24MHz.
