Problem
1. Why does the 68000 require only one address strobe, AS*, but two data strobes, UDS* and LDS*? Would a single pair of data strobes be sufficient?
2. Suppose that AS* did not exist. Can you design a circuit that indicates that a new address is on the address bus (you cannot use DS*),
3. In a 68000 read cycle, AS* and UDS*/LDS* are asserted simultaneously, In a write cycle, UDS*/LDS* is asserted approximately one clock cycle after AS*. What is the reason for this?
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.
