Problem
1. Since the 68020 has a data bus sizing mechanism and can access word and longword values at even boundaries, does an address error exception have any real meaning in 68020 systems?
2. How does the 68020 enhance the 68000's CHK exception?
3. What are the format and the vector offset stored in word four of a 68020 stack frame and how are they used (either by the 68000 itself or by the programmer)?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
