Document #: 38-06040 Rev. *A
33. “X” = “Don’t Care,” “H” = V
34. ADS, CNTEN, CNTRST = “Don’t Care.”
35. OE is an asynchronous input signal.
36. When CE changes state in the pipelined mode, deselection and read happen in the following clock cycle.
37. CE
38. Data shown for flow-through mode; pipelined mode output will be delayed by one cycle.
39. Counter operation is independent of CE
