Notes
Document #: 38-06056 Rev. *C
35. “X” = “Don’t Care”, “H” = V
36. ADS, CNTEN, CNTRST = “Don’t Care”.
37. OE is an asynchronous input signal.
38. When CE changes state In the pipelined mode, deselection and read happen in the following clock cycle.
39. CE
40. Data shown for flow through mode; pipelined mode output is delayed by one cycle.
41. Counter operation is independent of CE
