85. Which of the following statements best describes the operation of a synchronous up-/down-counter?
(a) The counter can count in either direction, but must continue in that direction once started. (b) The counter can be reversed, but must be reset before counting in the other direction. (c) In general, the counter can be reversed at any point in its counting sequence. (d) The count sequence cannot be reversed, once it has begun, without first resetting the counter to zero.
Answer
