ELEC2220 Computer Systems Spring 2021 Homework # 3 (Submit a single PDF file online (Canvas) before 10:50 a.m. on 2/12/21) EQU 1. Create a Code Warrior project using Create New Project (choose HCS12HCS12C Family+MC9S12C32, Full-chip Simulation and Absolute Assembly). 2. Type in the program given below using the template, main.asm. . Comment out the include statement. Add the statement "RAMStart EQU $0900 right above the statement "ROMStart EQU $4000. Replace the variable definitions in the template by the variables in this homework. Replace the instructions in the template by the instructions in this homework. Do not leave any space in the beginning of a statement with the directive EQU, DS or DC. Leave at least a space before each instruction. Do not remove the statements "XDEF Entry, Startup" and "ABSENTRY Entry," the labels "En- try" and "Startup," and the "Interrupt Vectors" section in the template. 3. Compile and run it using "Single-Step to find out what each instruction does. Make sure that the memory contents starting at the address $900 are displayed in the memory window.
