  1. What is the difference between the 190 and 191?
  2. Which edge causes the count to advance?
  3. What level must be applied to the up-down pin to make it count up? Down?
  4. Is the load control synchronous?
  5. What are the P0 - P3 inputs used for?
Thanks SOOOO MUCH

loganfife is correct. This does appear to be a class assignment that is an exercise in interpreting a manufacturer's datasheet. As such you should be able to quickly find the answers to the questions you have been given by referring to the manufacturer's datasheet.
