+* 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.
