∗^{: f(XIN) = 20 MHz when the clock source selet bit = “1”}
Notes 1: When the clock source select bit = “1”, tc’s minimum limit is 50 ns.
2: When the clock source select bit = “1”, set tw(H)/tc and tw(L)/tc ratios to 45 to 55 %.
3: Since the values depend on external clock input frequency f(XIN), calculate them using the bus timing data formula on the page after
the next page.
