Notes:
Document #: 38-06039 Rev. *A
32. “X” = “Don’t Care,” “H” = V
33. ADS, CNTEN, CNTRST = “Don’t Care.”
34. OE is an asynchronous input signal.
35. When CE changes state in the pipelined mode, deselection and read happen in the following clock cycle.
36. CE
37. Data shown for flow-through mode; pipelined mode output will be delayed by one cycle.
38. Counter operation is independent of CE
