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