Chapter 9 - Review Questions:

1. Review different chip packaging types. What is SPDIP package?
3. What is the purpose of Data Latch in IO ports? output is used to output the data clocked by WR pin
4. How does a D-type FF work? Construct its truth table.
5. How can D-type FF be used to make a frequecny divider? Show the circuit
6. Explain what we mean by a port being current sinking and sourcing/ Draw the circuit for each case.
7. What do we mean by IO PORT Multiplexing. Give an example.
8. What is the difference between Common Anode (Active High) and common cathode (active Low) – draw the circuit for each case.
9. Explain how 7-segment devices work and interfaced to a PIC. Show teh schematic.
10. Measure current provided by the port connected to 7-segment - later
