-* Title: Star Fill (In Memory) Homework #1
-*
-* Objective: CMPEN472 Homework #1 demonstration program. Fill 225 bytes of memory with '*'.
-*
-* Revision: V1.0
-*
-* Date: Jan. 22, 2025
-*
-* Programmer: Jacob McDonnell
-*
-* Company: The Pennsylvania State Universtiy
-* Electrical Engineering and Computer Science
-*
-* Algorithm: While Loop demo of HCS12 Assembly
-*
-* Register Use: A accumulator: character to be placed in memory
-* B accumulator: counter of filled memory locations
-* X register: pointer to memory location to fill
-*
-* Memory use: RAM locations $3000 to $30E1
-*
-* Input: No input, data and parameters are hard coded.
-*
-* Output: Memory locations $3000 to $30E1 are filled with '*' character.
-*
-* Observation: This program is designed for instruction purpose.
-* This program can be a template for other loop based code.
-*
-* Comments: This program is developed and simulated using CodeWarrior Development Software.
